  • Market for a new wave of demand for waterproof carton
    In recent years, with the people's living standards improved, increasing demand for packaging products. Corrugated packaging container as a commodity, not only to guarantee safety in the transportation of goods, but also play a beautification products, increase of added value, promote sales role. Especially in recent years appearing on the market a variety of printed cartons exquisite new moisture-proof coating, in large part to improve product quality, packaging cartons, and a fundamental solution of the carton packaging Yi Chao, easy to mold, easy to loss issues. Corrugated to withstand wet or grease penetration, the intensity will rapidly decrease. Shape, stiffness owing to the damp change. Because after the carton box by water infiltration, compressive strength, bursting strength will be greatly decreased, which would seriously affect the quality of packaging. For example: at 95% relative humidity environment, the corrugated boxes will lose 2 / 3 of the original rhyme strength, corrugated box will be the collapse of the entire cross. Currently boxes with waterproof properties of the market demand is growing, especially in the vegetable, food, household appliances, industrial products, packaging, application of a gradual increase. Export products, especially the rapid growth of water-resistant carton usage, which greatly promoted the development of corrugated box manufacturing industry.
    Waterproof cardboard is resistant to water damage the strength of the general term for cardboard. Production of corrugated box for moisture, in addition to protection against water, wet packing, the main is to prevent infiltration of water on the box itself.
    Moisture-proof, waterproof corrugated board development concern. As the corrugated box to absorb moisture, or water-absorbent stacking strength will result in significant decline, has become a carton manufacturing enterprises need to be solved important issues. The most common way is to pull in the original paper coating agent. Was first painted in cardboard boxes on the use of tung oil in order to achieve water-proof, moisture-proof effect. Chitosan acetic acid solution after impregnation and acetic anhydride treatment, converted into chitin, apply the original paper and also has good moisture-proof, waterproof effect. The use of paraffin wax, microcrystalline wax, polyethylene wax, beeswax, white wax, carnauba wax, montan wax and other animal and plant wax, apply on board by the emulsion can be moisture-proof and waterproof on the same due to low cost, is currently the most widely used approach to . However, this method of surface characterization of anti-poor, low-gloss, you can join the propylene-based polymer, phenolic resin, epoxy resin, amino resins, poly amide, poly-amino acid alcohol and high-linked thermoset polymers such as polyvinyl chloride , made of composite structures of the pull agent for the impregnation cardboard, can greatly improve the cardboard waterproof and moisture resistant. Waxing corrugated board is not conducive to recovery, the EU has begun to limit the use of. Another pull aqueous chromium trioxide is used in the alcohol - hydrochloric acid solution, restore, and stearic acid with is made of both anti-mildew, anti-pollution and other features. At present there are different formulations on the market pull agent to sell. If the resin, starch or plastic type moisture-proof agent to join the pulp caused by moisture within the copy paper, carton of natural right to produce the most convenient, although this number to increase the cost of base paper, but the total cost is still cost-effective. Toyo Steel Co., Ltd. has made to develop 0.02mm ~ 0.05mm thick pure iron foil by zinc, nickel or tin anti-rust treatment, and kraft paper, polyethylene film extruded with the compound into a composite board, used to make cartons, not only waterproof, moisture-proof, but also electromagnetic shielding, anti-static, especially for aquatic products, fruits and vegetables, electronic instrumentation, semiconductor devices and machinery and electronic products packaging. Aluminum PVC film and the kraft paper cartons post-production, also has a waterproof, moisture-proof function.
    Moisture-proof packaging technology
    Air humidity is caused by corrosion products, deterioration of the important factors. Wet products and other items of industrial hazards mainly to make metal rust, so that non-metallic products taken place mildew into deliquescence. Some organic materials, the surface moisture swelling, deformation, blistering, not only affect the appearance, but also to mechanical performance. In order to prevent items in the production, transportation, storage, use a qualitative change in the course of damp to take protective packaging, as moisture-proof packaging.
    Packaging materials or containers depends on the moisture resistant material or container moisture penetration. Packaging material moisture permeability means: per unit area within the unit, asked by the weight of the water vapor. Water vapor permeability of packaging materials and material types, processing methods and material thickness. In order to improve performance, moisture-proof packaging materials, reducing its moisture permeability is often a different soft multi-layer composite material, made of composite film. Commonly used packaging materials and composite packaging material moisture permeability in the table below.
    The moisture-proof packaging in general there are four: the first one is being packaged in order to prevent loss of moisture water products to ensure product performance and stability, using a certain humidity, moisture-proof transparent packaging materials packaging; the second is to prevent the packaged product moisture absorption of moisture in the containers placed a certain amount of desiccant to absorb the package into the package when the water will keep humidity within a certain range. Desiccant commonly used are: silica gel, molecular sieve, activated alumina. This method requires that the container can be sealed, so that the container interior space with the outside air isolation. This method is suitable for small packing cases; third is accused of space through continuous or intermittent moisture detection and control of space will be charged to maintain the humidity within a certain range, achieving the purpose of supplies and equipment dry and sealed . This method is suitable for large products, moisture-proof packaging (such as large equipment, automobiles, airplanes, etc.), can be used such as recycling dehumidification drying and condensation control methods; The fourth is through sealed containers within the vacuum method of realization of moisture

  • China HengTaiDa Packaging Industry Co.,Ltd got the news from PackIndustry.com
    The average price of rubber raw materials across the globe has risen by 15 per cent in 2009, says Rubber World Industries (RWI), the leading manufacturer of closed-cell rubber insulation 'Gulf-O-flex' in the Gulf and South-East Asia, and part of the international business conglomerate, the Memon Group of Companies. Amidst the upward movement of global prices, RWI, which accounts for 86 per cent of the Middle East rubber insulation market share, has committed to maintain its prices and ensure sufficient supply of rubber insulation products across the region, including pipes, sheets and other rubber-derived products.

    Following a long period of continuous decline, the price of rubber raw material in the world market has seen an increase in the second quarter of 2009. Furthermore, three of the largest rubber producers in Southeast Asia - Thailand, Malaysia and Indonesia, agreed to cut down their exports to push up the export price. Rubber producers and exporters have also decided to cut down output, which could translate to a 6.2 per cent drop in world rubber production in 2009 to hit 9.36 million tons. Amidst increasing global rubber raw materials prices, RWI maintains a positive outlook on the regional market taking pioneering efforts to enhance its processes and production capacity.

    "Amidst present challenges, we are strengthening our efforts to increase our production by 600 containers to sufficiently address the need for rubber insulation products in the region," said Abu Baker Shaikhani, Managing Director, Rubber World Industries, and Chairman of the Memon Group. "We expect the region to witness a steady increase in the demand for high quality rubber insulation products, which motivates us to explore more technologies to further enhance the quality of our products and the efficiency of our processes."

    RWI has also recently revealed its expansion goals, which is to be able to produce 3,600 containers by 2013, thereby cementing its leading position as the source of high quality products for major property developments by real estate leaders in the UAE. As the only producer of rubber insulation in the Middle East region, RWI delivers a versatile range of rubber insulation products that meet the requirements in the oil and gas fields, construction, shipping and automobile industries. RWI products are used in more than 90 countries, including the US, Germany, Russia, Canada and Singapore.

  • Chinese proverb says "Food doesn't harm you but careless words may." However, you can no longer say "food doesn't harm you". Nowadays, people choose food with exceptional caution. They buy vegetables with bugs and soak them for half an hour to avoid pesticides. They won't choose white noodles because artificial pigment has been added, and the same with chilli sauces. However, no matter how smart you are, there is no way you can stay away from unsafe foods.

    Over the past year there have been a number of food safety stories from China. The stories below demonstrate the risk to consumers, but also to investors in an industry that is now under enormous pressure to clean up its act. With a new food law on the drawing board for 2009, the question remains whether the 'Made in China' brand can claw its way back into export (and even domestic) markets.

    Sodium cyclamate in jujubes: The Urumqi Health Authority reported the discovery of illegally produced "red jujube" in the Toutunhe District on 18 August. Authorities found 10 tons of raw materials and finished products at the manufactory site. They also uncovered 14 bags of sodium cyclamate, 11 bags of saccharin-sodium, as well as a bag of alum. Workers turned "green jujubes" (raw jujubes) to "red jujubes" (ripe jujubes) by adding soy sauce, and then used saccharin-sodium and sodium cyclamate to make them sweet and tasty. Some of the products made it to market before the authorities could halt sales.

    "Do not eat oranges": So said a text message that spread rapidly by mobile phone in Guangyuan, Sichuan, around 20 October. The message said that "there are maggots in Guangyuan oranges" and that people shouldn't eat them. The government tried to hose down what was eventually reported as a rumour, but the case triggered panic among some consumers.

    People in China are worried about food safety; and with good reason. In response, China's top legislature approved the Food Safety Law on 28 February 2009, providing a legal basis for the government to strengthen food safety control "from the production line to the dining table." The law, which goes into effect later this year on 1 June will enhance monitoring and supervision, toughen safety standards, recall substandard products and severely punish offenders.

    A blue paper issued by the Chinese Academy of Social Sciences on 2 March states China should strengthen risk management to ensure food safety. The system, it says, should focus on evaluating the biological, chemical and physical dangers existent in food and food additives.

    An important component of the Food Safety Law is that it prohibits the Food Safety Supervision and Management Department from giving companies or products an exemption for food tests. This would seem vital now to resuscitate trust in 'Made in China' food products.

    Food safety is synonymous with a healthy life, so it is essential now that China (including food growers, manufacturers, retailers and various monitoring department) build trust.

  • Other plastics emerged in the prewar period, though some wouldn't come into widespread use until after the war.

    By 1936, American, British, and German companies were producing "polymethyl methacrylate" (PMMA), better known as "acrylic."  Although acrylics are now well-known for the use in paints and synthetic fibers, such as "fake furs," in their bulk form they are actually very hard and more transparent than glass, and are sold as glass replacements under trade names such as "plexiglas" and "lucite."  Plexiglas was used to build aircraft canopies during the war, and it is also now used as a marble replacement for countertops.

    Another important plastic, polyethylene (sometimes known as "polythene") was discovered in 1933 by Reginald Gibson and Eric Fawcett at the British industrial giant Imperial Chemical Industries (ICI).  This material evolved into two forms, low density polyethylene (LDPE) and high density polyethylene (HDPE).

    Polyethylene is cheap, flexible, durable, and chemically resistant.  LDPE is used to make films and packaging materials, including plastic bags, while HDPE is used more often to make containers, plumbing, and automotive fittings.  While PE has low resistance to chemical attack, it was found later that a PE container could be made much more robust by exposing it to fluorine gas, which modified the surface layer of the container into the much tougher "polyfluoroethylene."

    Polyethylene would lead, after the war, to another material, "polypropylene" (PP), which was discovered in the early 1950s.  It is common in modern science and technology that the growth of the general body of knowledge can lead to the same inventions in different places at about the same time, but polypropylene was an extreme case of this phenomenon, being separately invented about nine times.  It was a patent attorney's dream scenario, and litigation wasn't resolved until 1989.

    Polypropylene managed to survive the legal process, and two American chemists working for Phillips Petroleum of the Netherlands, Paul Hogan and Robert Banks, are now generally credited as the "official" inventors of the material.  Polypropylene is similar to its ancestor, polyethylene, and shares polyethylene's low cost, but it is much more robust.  It is used in everything from plastic bottles to carpets to plastic furniture, and is very heavily used in automobiles.

    Polyurethane was invented by Friedrich Bayer & Company of Germany in 1937.  It would come into use, after the war, in blown form for mattresses, furniture padding, and thermal insulation.  It is also used in non-blown form for sports wear such as "lycra."

    In 1939, I.G. Farben Industrie of Germany filed a patent for "polyepoxide" or "epoxy."  Epoxies are a class of thermoset plastics that form cross-links and "cure" when a catalyzing agent, or "hardener," is added.  After the war, they would come into wide use for coatings, "super glues," and composite materials.

    Composites using epoxy as a matrix include "fiberglass," where the structural element is glass fiber, and "carbon-epoxy composites," in which the structural element is carbon fiber.  Fiberglass is now often used to build sport boats, and carbon-epoxy composites are an increasingly important structural element in aircraft, as they are lightweight, strong, and heat-resistant.

    Two chemists named Rex Whinfield and James Dickson, working at a small English company with the quaint name of the "Calico Printer's Association" in Manchester, developed "polyethylene terephthalate" (PET or PETE) in 1941.  It would be used for synthetic fibers in the postwar era, with names such as "polyester," "dacron," and "terylene."

    PET is more impermeable than other low-cost plastics and so is a popular material for making bottles for Coke and other "fizzy drinks," since carbonation tends to attack other plastics, and for acidic drinks such as fruit or vegetable juices.  PET is also strong and abrasion resistant, and is used for making mechanical parts, food trays, and other items that have to endure abuse. PET films, trade-named "mylar," are used to make recording tape.

    One of the most impressive plastics used in the war, and a top secret, was "polytetrafluoroethylene" (PTFE), better known as "teflon," which could be deposited on metal surfaces as a scratchproof and corrosion-resistant, low-friction protective coating.  The polyfluoroethylene surface layer created by exposing a polyethylene container to fluorine gas is very similar to teflon.

    A Du Pont chemist name Roy Plunkett discovered teflon by accident in 1938.  During the war, it was used in gaseous-diffusion processes to refine uranium for the atomic bomb, as the process was highly corrosive.  By the early 1960s, teflon "non-stick" frying pans were a hot consumer item.

    Teflon was later used to synthesize the miracle fabric "GoreTex," which can be used to build raingear that in principle "breathes" to keep the wearer's moisture from building up.  GoreTex is also used for surgical implants; teflon strand is used to make dental floss; and teflon mixed with fluorine compounds is used to make "decoy" flares dropped by aircraft to distract heat-seeking missiles.

    After the war, the new plastics that had been developed entered the consumer mainstream in a flood.  New manufacturing was developed, using various forming, molding, casting, and extrusion processes, to churn out plastic products in vast quantities.  American consumers enthusiastically adopted the endless range of colorful, cheap, and durable plastic gimmicks being produced for new suburban home life.

    One of the most visible parts of this plastics invasion was Earl Tupper's "tupperware," a complete line of sealable polyethylene food containers that Tupper cleverly promoted through a network of housewives who sold Tupperware as a means of bringing in some money.  The Tupperware line of products was well thought out and highly effective, greatly reducing spoilage of foods in storage.  Thin-film "plastic wrap" that could be purchased in rolls also helped keep food fresh.

    Another prominent element in 1950s homes was "formica," a plastic laminate that was used to surface furniture and cabinetry.  Formica was durable and attractive.  It was particularly useful in kitchens, as it did not absorb, and could be easily cleaned of stains from food preparation, such as blood or grease.  With formica, a very attractive and well-built table could be built using low-cost and lightweight plywood with formica covering, rather than expensive and heavy hardwoods like oak or mahogany.

    Composite materials like fiberglass came into use for building boats and, in some cases, cars.  Polyurethane foam was used to fill mattresses, and styrofoam was used to line ice coolers and make float toys.

    Plastics continue to be improved.  General Electric introduced "lexan," a high-impact "polycarbonate" plastic, in the 1970s.  Du Pont developed "kevlar," an extremely strong synthetic fiber that was best-known for its use in bullet-proof vests and combat helmets.  Kevlar was so remarkable that Du Pont officials actually had to release statements to deny rumors that the company had received the recipe for it from space aliens.

    One of the most potentially important new developments in plastics is circuits made out of plastics called conductive polymers.  Electronic circuitry fabricated using plastics or other materials that could be simply printed on a substrate could be incredibly cheap, opening the door to throwaway electronic devices that would cost pennies, or to applications hardly dreamed of now.

    So far, electronic devices made with such materials have not been acceptable for production but, in 2001, prototypes of flat-panel displays based on such technologies were being publicly demonstrated, with predictions of commercial introduction in two or three years.
