How To Store PETG Shrink Film?
PETG shrink film is a sensitive material that can be affected by certain environmental factors. To ensure that it maintains its quality and performance, it's important to store PETG shrink film
properly. Here are some guidelines for storing PETG shrink film:
1、Store in a cool, dry place: PETG shrink film should be stored in a cool, dry place away from direct sunlight, heat, moisture, and humidity. Ideal storage temperatures are between 10°C and 30°C (50°F and 86°F) with a relative humidity of 50% or less.
2、Avoid exposure to UV light: PETG shrink film should be kept away from exposure to UV light, which can cause discoloration and degradation of the film. If possible, store the film in a dark or shaded area.
3、Keep in its original packaging: PETG shrink film should be kept in its original packaging, which is designed to protect it from moisture, dust, and other environmental factors. If the original packaging is damaged or compromised, it's recommended to repackage the film in a similar protective covering.
4、Store flat: PETG shrink film should be stored flat to avoid creasing, wrinkles, or deformation of the film. If the film is stored in a rolled or folded position, it may become difficult to unroll or straighten, and this can negatively affect its performance during the shrinking process.
5、Rotate stock: PETG shrink film has a limited shelf life, and it's important to use the oldest stock first. It's recommended to rotate the stock on a first-in, first-out (FIFO) basis to ensure that the film is used within its recommended shelf life.
By following these guidelines, you can ensure that your PETG shrink film is stored properly and remains in good condition for use in your packaging applications.
What Is The Standard Of PETG Shrink Film?
PETG shrink film is a type of plastic film made from PETG resin, which is a copolyester material that offers excellent clarity, high shrinkage rates, and good strength and durability. There are several industry standards for PETG shrink film, including the following:
1、FDA compliance: PETG shrink film
is regulated by the U.S. Food and Drug Administration (FDA) and must comply with FDA regulations for food contact applications. PETG shrink film is often used in food packaging applications because of its clarity, safety, and performance.
2、ISO 9001: The International Organization for Standardization (ISO) has a standard for quality management systems called ISO 9001. PETG shrink film manufacturers may choose to be certified to this standard, which ensures that their products meet certain quality and safety requirements.
3、ASTM D3475: The American Society for Testing and Materials (ASTM) has a standard for transparent and opaque plastic films used for packaging applications, called ASTM D3475. PETG shrink film can be tested to this standard to ensure that it meets the required specifications for tensile strength, elongation, tear resistance, and other physical properties.
4、RoHS compliance: PETG shrink film may also be regulated by the Restriction of Hazardous Substances (RoHS) Directive, which restricts the use of certain hazardous substances in electrical and electronic equipment. PETG shrink film that is RoHS compliant is free from substances such as lead, cadmium, mercury, and hexavalent chromium.
Features Of PETG Shrink Film
PETG shrink film is a versatile and high-performance material that offers several features and benefits for a wide range of packaging applications. Here are some of the key features of PETG shrink film:
1、High clarity: PETG shrink film
has excellent clarity, which allows the packaged product to be visible and attractive to the consumer.
2、High shrinkage rate: PETG shrink film has a high shrinkage rate, which allows it to conform tightly to the shape of the product, creating a tight and secure package.
3、Good tensile strength: PETG shrink film has good tensile strength, which allows it to resist tearing and puncturing during packaging and transportation.
4、Good barrier properties: PETG shrink film has good barrier properties against oxygen, moisture, and other contaminants, which helps to protect the packaged product from spoilage, contamination, or damage.
5、High temperature resistance: PETG shrink film has a high temperature resistance, which makes it suitable for use with heat guns or shrink tunnels during the shrinking process.
6、Good printability: PETG shrink film has good printability, which allows for high-quality printing of custom graphics or branding on the film.
7、Environmentally friendly: PETG shrink film is recyclable and can be used as a more sustainable packaging option compared to other non-recyclable materials.
