PETG plastic: the right choice for your shrink film business

What is Shrink Film?

Shrink film is a film that can shrink significantly when heated, thereby tightly wrapping items and maintaining its shape for a long time. The shrink film is designed based on the principle of stretching and orienting the polymer molecular chains, and is formed by rapid cooling and setting. Shrink film is used in the sale and transportation of various products to stabilize, cover and protect the product.

At present, the largest application market of shrink packaging materials is the food industry, which is widely used in the packaging of various fast food, lactic acid food, beverages, beer cans, etc. In non-food fields, the application of shrink film is also increasing, such as cosmetics, daily necessities, pharmaceutical products, electronic products, toys, building materials, handicrafts, etc.

Common shrink film materials on the market include POF, PE, PET, PVC, and OPS.

What is PETG plastic?

PETG plastic is a thermoplastic polyester that delivers significant chemical resistance, durability, and moldability for manufacturing. PETG is an adaptation of PET where the ‘G’ stands for glycol such as CHDM or NPG, which is added at a molecular level to offer different chemical and optical properties.

Advantages of PETG Shrink Film

PETG shrink film is made of PETG plastic, which can achieve a final shrinkage rate of greater than 75%. It can be made into complex container packaging and achieve a tight fit with the container. It is suitable for shrink packaging of beverage bottles, food and cosmetics, and shrink labels for electronic products. It can change the shortcomings of traditional packaging films that are opaque or have poor packaging effects, and meets the current packaging market demand for bottle nutrition.

PETG shrink film has excellent processability, high plastic absorption, high transparency, high gloss, low haze, non-toxic, odorless, high strength, and high thermal shrinkage rate. Its natural shrinkage rate is low during storage, which improves the packaging effect. PETG shrink film is transparent and beautiful. It can fully reflect the image of the product, improve the appearance of the product, facilitate product advertising, and enable the product to win consumers with beautifully printed outer packaging. At the same time, it can well shows a good image of the manufacturer.

A Nielsen study shows that uniquely contoured bottles with heat-shrinkable labels that fit closely to the bottle are more attractive to consumers and can increase purchase rates than flat films. Many international companies, such as Coca-Cola, Pepsi, Nestlé and Unilever, are gradually converting their outer packaging shrink films to PETG plastic, which have gained good certification in the consumer market.
