Australia's CUB company with a single layer of PET bottles packaged 500ml beer, room temperature can be maintained for 4 weeks, and the company uses epoxy amine coated PET bottle packaging 500ml beer, shelf life of up to 100 days. However, the current production efficiency of the technology is low, the surface coating technology to provide the barrier properties are often affected by the specific surface area of ??the bottle, the coating will be due to creep caused by uneven thickness, or by regular friction leaving the barrier The The coating also exists on the safety of food issues, these issues need to be further studied to solve the cost also need to be further reduced, it will help the market process.

(3) Blending of different materials By mixing other organic polymers or inorganic materials in a polymer to improve and equalize the performance of each component, overcome the weakness of a single component to achieve the desired properties of the ideal polymer material , Is the development of new plastic, one of the most simple shortcuts. For PET high barrier materials, this method has also been extensively and extensively studied, such as EVOH, PVDC, PE, PP, PA and PEN in organic polymers are used for blending with PET to improve material barrier properties. progress. Studies have shown that the barrier properties of the blends strongly depend on the morphology of the blends. The main reason why a variety of material blends can improve the barrier properties is to increase the channel aspect ratio of the molecules in the polymer when the molecules diffuse through the dispersed phase (high barrier material layer). The high barrier properties correspond to the blends with large radial deformations in the dispersed phase. At present, the most successful organic PET blend material is a kind of PEN (polyethylene naphthalate) which is similar to PET structure and has higher barrier property and good compatibility. It has excellent barrier properties and mechanical properties, Can be used alone for the preparation of plastic beer bottles, but because of its high price (pound price
For 8 dollars / Kg), it is difficult for customers to accept. As a raw material, the amount of PEN used as a raw material is small, but it can be made thinner, which can greatly improve the barrier property of PET while being inexpensive and easier to be accepted by the market and the user. At the same time, a variety of nano-inorganic materials are also used to blending with PET to improve the material barrier properties and mechanical properties, such as nano-montmorillonite, silica, titanium dioxide and nano-zinc oxide are used for blending with PET, Most of its role as a nucleating agent, a small amount can increase the nucleation of materials, improve the ability of directional crystallization, thereby improving the mechanical properties and barrier properties.
