Lesui And PET

Lesui Industry has been engaged in the PET industry since 2013, focusing on the production of mid-to-high-end food packaging containers. The products cover fruit and vegetable boxes, fresh boxes, pastry boxes, set containers, etc. It owns two brands of "Le Sui" and "Vege and Fruit Le".

In recent years, the company's output value has maintained a growth rate of about 100%. At present, the market share in the high-end packaging segment of fresh fruits and vegetables is nearly 35%, ranking first in the industry.

What's the PET?

It has excellent physical and mechanical properties in a wide temperature range, the long-term use temperature can reach 120 ° C, and the electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, creep resistance, fatigue resistance, Friction resistance and dimensional stability are very good. PET has an ester bond, which will decompose under the action of strong acid, strong alkali and water vapor, and has good resistance to organic solvents and weather.

Advantages of PET

1. It has good mechanical properties, the impact strength is 3 to 5 times that of other films, and the folding resistance is good.

2. Oil resistance, fat resistance, dilute acid, dilute alkali, and most solvents.

3. It can be used for a long time in the temperature range of 55-60°C. In short-term use, it can withstand high temperature of 65 °C and low temperature of -70 °C, and has little effect on its mechanical properties at high and low temperatures.

4. The permeability of gas and water vapor is low, and it has excellent gas barrier, water, oil and odor properties.

5. High transparency, can block ultraviolet rays, and have good gloss.

6. Non-toxic, tasteless, good hygiene and safety, can be directly used for food packaging.

Applications of PET

1. Food packaging materials

PET material is widely used in the field of food packaging because of its excellent gas barrier, water, oil and odor properties, such as vegetable packaging, fresh meat packaging, beverage bottles, etc.

2. Industry and Agriculture

Because of its good creep resistance and fatigue resistance, high surface hardness and mechanical properties, it can also be processed into parts engineering materials for the automotive industry, construction ropes, pesticides and fertilizers packaging materials, etc.
