What Is the Difference Between the Packaging Material APET And PETG And PET?

APET is a blister material, the full chemical name is non-crystallized polyethylene terephthalate. APET blister material: polyester sheet (PETSHEET), also known as polyester rigid tape, is a thermoplastic environmentally friendly plastic products, its edges and waste products can be recycled, its chemical elements are the same as paper for carbon, hydrogen, oxygen, is a degradable plastic. APET environmental film is widely used in packaging for cosmetics, food, electronics, toys, printing and other industries, such as a variety of high-grade blister packaging, folding boxes, plastic tubes, window sheets, etc.

The advantages of APET are as follows: firstly, good folding resistance, APET film does not show self-cracking creases like other materials, which makes it more suitable for documents and other surfaces; secondly, lighter specific gravity, APET is 3.7% lower than general materials; thirdly, APET film has high transparency, especially good gloss; fourthly, high strength, APET film The strength of APET film is more than 20% higher than others; fifth, low temperature resistance, can withstand tens of degrees Celsius below zero without brittle crack. Therefore, APET products are pollution-free, crystal-free, high transparency, good gloss, strong impact resistance, etc.

They can be widely used in blister, folded boxes, cylinders and other fine packaging and various printing window sheets. PETG is a highly transparent copolymer polyester plastic material. It has high transparency, good toughness and impact strength, excellent low temperature toughness, high tear resistance and good processing performance, excellent chemical resistance. It can be processed by traditional extrusion, injection moulding, blow moulding and blister moulding methods. It is widely used in the sheet, high performance shrink film, bottle and profile markets; it can be used to produce toys, household utensils and medical supplies; it has passed the US FDA standard on food contact and can be used in food, pharmaceutical and cosmetic packaging.PET is mainly used in soft drink packaging for soft drinks. PET has nearly 100% of the market for 2 litre packaging non-recyclable containers, 1.5 litre, 1 litre, 0.5 litre and smaller PET bottles have also gained widespread acceptance.

PET is used in food, alcohol, detergents. The demand for PET is expected to continue to grow for uncarbonated beverages and industrial product packaging. Foods being packaged include mustards, gum products, peanut butter, condiments, cooking oils, cocktails and fruit juice concentrates. New colours, particularly Weibull-coloured PET in pharmaceuticals. Vitamin and detergent packaging is hugely popular.

One of the newest and fastest growing applications for PET containers is food or beverage packaging, which requires filling at high temperatures. Many foods, especially fruit or high fruit content foods or beverages, must be packaged at 180F or higher. This provides pasteurisation (sterilisation) of the product and the container at the time of filling. Usually oriented containers, such as those used for soft drink bags for soft drinks have a tendency to shrink and deform when subjected to high temperatures above 160T, which is due to a certain amount of stress relaxation. The production of containers in stretch blow moulding when the stress concentration. Improvements in processing heat resistance technology has been developed, often referred to as “heat-setting” technology.

Depending on the particular process, there are a number of processing technology details, which are highly patentable, whereby containers suitable for filling at 190 to 195F can be produced. Products requiring packaging with such characteristics are pure fruit juices. High juice content beverages, teas, certain isotonic and sports drinks, flavourings, fruit juice concentrates and certain mineral waters.Other end uses for PET are the wide range of extrusion-coated and extrusion-formed films and sheets.PET is used as an extrusion-coating material for bakeable cardboard packaging and, in addition, crystalline PET (CPET) can also be used as a base material for making trays in ovens.PET films are usually biaxially oriented and are used for X-ray and other photographic films, meat and cheese packaging, magnetic tapes, electrical insulation, printing plates and bags for bottles. Non-crystalline, unoriented PET films and sheets are beginning to expand for use in moulded containers, trays, foam products and beverage cups, etc.
