In 1996, the United States had a market share of 28.7 billion U.S. dollars. It is estimated that by the year of 2003, it will increase to about 44 billion U.S. dollars, with an annual growth rate of about 5-6%. The reasons for the increase include: adapting to the needs of workers or professional women to take home the meals in plastic bags, carbonated drinks and fruit juices; packaging for new drugs or medical equipment; a sharp increase in non-prescription drugs; reusable packaging; On behalf of the non-fat food high barrier packaging. In general, food packaging accounts for more than half of the packaging market, followed by medical equipment and drug packaging. In the future, the development trend of polymer packaging materials will be as follows: From a pocket-sized package to a soft package, to reduce waste and costs. Future polymer materials must improve puncture resistance, heat sealability and barrier properties; low cost polyesters will replace PS, paper and aluminum; high transparency transparent barrier materials and their coating technologies; decomposable plastics Wait. The development trend of polymer packaging materials Polymer packaging materials are mainly synthesized with gold olefin catalysts. Gold metal catalysts are a high-efficiency and high-selection single-active point solution media. Therefore, the synthesized polymers mostly have two major advantages of narrow molecular weight distribution and low micro-catalytic content, and are very suitable for use in food and pharmaceutical packaging. The following is its latest development trend:
1. The new generation of polyethylene (mPE) has entered the market for several years and has been used in packaging mainly for its low heat seal strength, high initial heat seal strength and low haze, and is mainly used for heat sealing layers.
2. The new generation polypropylene (mPP) is a new material that is not the same as the current PP grade. In general, his melting point is lower (less than 160°). The current commonly used electronic packaging containers Gao Jiejing.
3, a new generation of polystyrene (sPS) a new generation of polystyrene, also known as para-polystyrene, which has a high transparency (when made into a thin film), also has a higher melting point and high gas barrier Therefore, it will also be considered for barrier film use.
4. New Generation of Polyethylene and Polystyrene Polymers (ESI) The new generation of Polyethylene and Polystyrene Polymers (ESI) successfully controlled the structure and structure of ethylene and styrene in the main chain, breaking through the previous two types of single The disadvantage of the body is not easy to copolymerize.
5. The new generation of cyclic olefin copolymer (mCOC) The cyclic olefin copolymer has changed the previous impression that the polyolefin will crystallize and is not transparent enough. It combines the advantages of crystallinity and amorphous polymer, such as high transparency. , High heat resistance, excellent optical and electrical properties, low water absorption and water permeability, biocompatibility, and small amount of leachables provide excellent space for application developers. Polymers containing cyclic olefin monomers have been known for decades, but due to the difficulty in controlling the homogeneity and molecular weight of the polymer during synthesis, the proportion of impurities generated is often too high and the yield cannot be increased. There are few truly commercial applications available. The appearance of metallocene catalysts has greatly increased the ability to control the molecular structure of copolymers, creating a whole new opportunity - the soft linear olefins are co-polymerized with hard cyclic olefin monomers and can be freely adjusted to their proportions. The common advantages of amorphous and crystalline polymers are shown in the table below.
The new generation of cyclic olefin copolymers has the characteristics of high heat resistance, high transparency, low chromatic aberration, solvent resistance, blood compatibility, low dissolution property, and sterilization that can be used in a variety of ways in general to facilitate recycling and disinfection. In addition, cyclic olefin copolymers are resistant to general drug tests, so they are very promising in the application market for medical devices and parts (syringes, medical and drug testing discs, pharmaceutical discs).
The principle of gas barrier is roughly two series: one is the passive negative partition (that is, the use of low gas permeability of raw materials to achieve the purpose, and the other is active barrier (that is, the addition of inhalable material). Representative materials include 1 above-mentioned COC and other single-layer material of 2 layers structure material--micron-sized plyolefine/PET, Nylon, EVOH's Sealer and nano-series Nylon-Cley series, 3 co-extruded Nylon-containing, PET , EVOH multi-layered film, 4 vapor-deposited SiOx film.The current domestic with 2,3,4 kinds of film applications, the first film has not yet begun to use.These films are imported or homemade, the amount of use In Europe and the United States, there are significant growth trends.Examples of packaged sandwiches in Tennessee, United States, illustrate the excellent effects of gas-barrier soft packaging.This new product is a combination of Nylon and EVOH. It can be increased to 30 days, some even as high as 60 days, and the loss rate of its product (food) dropped from 20% to 5 to 6%, thus reducing the company’s loss of USD 700,000.
PET's Emerging Applications PET is a resin familiar to the packaging industry. With the largest PET production base in Taiwan, it will be able to significantly increase economic efficiency if PET's excellent performance is used. For example, three-fold egg packaging uses PET as packaging material.
1, three-fold egg packaging a packed three-fold PET egg packaging, mainly to take PET's high transparency, environmental protection and ease of printing, and also do not have to apply adhesive properties, can reduce the egg loss rate of 5% PS Foam cannot reach 1% (PS Foam is 2 to 3%). Although the price of PET packaging is as high as 18 cents/pc, and PS Foam and paper packaging are 6 cents/pc and 7.5 cents/pc, respectively, but for a price of only 1.89 to 2.99 US$ per cartridge, it should be Is an optional packaging material.
The new cooperation model of the packaging industry The packaging industry is the last link in all manufacturing industries, but it is the first to face customers. For this reason, packaging is often the first to be asked to improve quality (not to increase prices) or to cut prices (without sacrificing quality). Therefore, the difficulty of packaging is evident. With the promulgation of the FDA environmental regulations, the superiority of the new polymer will eventually be used in large quantities on the packaging. Under such circumstances, the upstream, middle, and downstream industries have gradually reached consensus - coexistence and co-prosperity, jointly funded research, shared profit models, and reduced the traditional mode of stress.
Concluding remarks Packaging is one of the behind-the-scenes heroes of product marketing, but it is also one of the most overlooked parties. Therefore, there are often competitions for the application design and packaging design of polymer materials and rewards for outstanding works. This is also for employees. An encouragement. How to improve the quality of products in the future requires the cooperation of the whole society.
