PET plastic sheet rolls for fruit and vegetable packaging

Introduction of PET plastic sheet rolls

PET plastic sheet rolls are a kind of plastic material rolls, the full name is polyethylene terephthalate rolls, also known as polyethylene terephthalate or polyester resin rolls. It is the most important variety of thermoplastic polyester. It is formed from the condensation polymer of terephthalic acid and ethylene glycol. Its surface is smooth and shiny, with good mechanical properties, high transparency, non-toxic and odorless.

PET plastic sheet roll series includes APET, PETG, and GAG. This is a new material plate product that has developed rapidly in recent years.

Excellent comprehensive performance, high transparency, good strength and easy post-processing are the advantages of PET plastic sheet rolls. Due to its good strength and the same thickness, the protective effect is obviously better than that of PVC sheets. If compared with the same strength, thinner PET sheets can be used. So although the price of PET sheets is higher. But the actual cost increase is not large. What’s more important is that PET sheets are crystal clear and can directly contact food, so they are often used to make packaging boxes for fruits and vegetables.

Advantage of PET plastic sheet rolls

Pet is a milky white or light yellow, highly crystalline polymer with smooth and glossy surface. It has excellent physical and mechanical properties in a wide temperature range, long-term service temperature up to 120 ℃, good electrical insulation, even in high temperature and high frequency.

Compared with the widely used PVC film, PET plastic sheet rolls have the following advantages:

1. Light specific gravity: The proportion of PET is 1.33, 1.38, 3.7% lower than that of PVC.

2. High strength: The strength of PET film is more than 20% higher than that of PVC film. It has better low-temperature impact resistance and can be brittle at -40°C, so it is usually replaced with a film that is 10% thinner than PVC film.

3. Good folding resistance: PET plastic sheet will not crack or crease like PVC, making it more suitable for product packaging.

4. High transparency: PET plastic films (PVC films have high transparency, especially shiny and blue) are better than PVC films and are more suitable for exquisite packaging.

5. Food grade: PET plastic sheet rolls can directly contact the surface of food non-toxic, so it is more suitable for fruit and vegetables and other packaging.

Production process of PET plastic sheet rolls

The production process of PET (Polyethylene Terephthalate) plastic sheet rolls involves several steps：Polymerization——Pelletizing——Extrusion——Calendering——Orientation——Heat Setting——Cutting and Winding.

Throughout the PET plastic sheet roll production process, quality control measures are implemented to ensure that the PET plastic sheet meets the required specifications in terms of thickness, transparency, strength and other relevant properties. The specific details of the process may vary depending on the equipment used and the customer’s application for the PET plastic sheet roll.
