Shandong High Temperature Resistance BOPET Clear film ,food grade printing PET for bag packaging

Characteristics:

Food-grade high-temperature resistant BOPET (biaxially oriented polyester) film has a series of unique properties that make it a preferred material for food packaging and other fields. The following are its main characteristics:

High strength and high rigidity:
BOPET film is treated with a biaxial stretching process, which gives it excellent strength and rigidity.
This high strength property makes BOPET film have good wear resistance and stretch resistance in applications.
Excellent heat resistance:
BOPET film can maintain good physical properties at higher temperatures.
Generally, BOPET film can withstand temperatures above 150°C. Some specific products such as food-grade reinforced BOPET film have a shrinkage rate of only 1.25% after being used at 120 degrees for 15 minutes, showing its excellent high temperature resistance.
This heat resistance makes it excellent in applications that require high temperature resistance, such as retort bags in food packaging.
Good dimensional stability:
The application of the biaxial stretching process makes BOPET film show good dimensional stability.
Even under high temperature conditions, BOPET film will not deform significantly, ensuring the stability of the shape and size of the packaged product.
High transparency and gloss:
BOPET film has high transparency and gloss, which makes it the best choice for applications with high visual requirements.
High transparency allows BOPET film to be used in packaging where internal items need to be observed, such as food packaging.
At the same time, its gloss also enhances the display effect of the product.
Excellent barrier properties:
BOPET film has excellent comprehensive water and gas barrier properties.
Its water barrier rate is similar to PE, its air permeability coefficient is extremely small, and its barrier to air and odor is extremely high, making it one of the fragrance-preserving materials.
Chemical resistance:
BOPET film shows good resistance to most chemicals, including acids, alkalis, oils and solvents.
This chemical resistance allows BOPET film to be used in applications in the chemical industry that come into contact with a variety of chemicals.
Safe and non-toxic:
BOPET film is odorless and non-toxic, meeting the requirements of food-grade packaging materials.
Its safety has been widely recognized and is suitable for various food packaging occasions.
In summary, food-grade high-temperature resistant BOPET film has broad application prospects in food packaging and other fields due to its high strength, high rigidity, excellent heat resistance, good dimensional stability, high transparency and gloss, excellent barrier properties, chemical resistance and safety and non-toxicity.
