High And Low Temperature Stretch Film

1. Product introduction

In modern industry and daily life, the choice of packaging materials is crucial. Especially for those products that need to be stored or transported under extreme temperature conditions, choosing the right packaging material is even more crucial. High and low temperature stretch film is a kind of high performance packaging material designed to meet this demand. It is capable of maintaining stable physical properties over a wide temperature range, ensuring the safety and quality of the contents of the package. High and low temperature stretch film is a packaging film specially designed to adapt to extreme temperature conditions. Such films are usually made by co-extruding multiple layers of different materials to achieve their physical properties and chemical stability at different temperatures. High and low temperature tensile film not only has good mechanical strength and barrier properties, but also has excellent temperature resistance characteristics, and can perform well in both high and low temperature environments.

2. Main features

High transparency: The high and low temperature stretch film has a high transparency, making the packaged product clearly visible, easy to identify and manage, but also improve the display effect of the product.

Environmental characteristics: The material of high and low temperature stretch film meets the requirements of environmental protection, can be recycled, and reduces the impact on the environment. In addition, due to its excellent barrier properties, the use of plastic materials can be reduced, further reducing the carbon footprint.

3. Application field

High and low temperature stretch film is widely used in food, medicine, chemical, electronic products and other fields, to provide customers with efficient and reliable packaging solutions.

Food industry: In the food industry, high and low temperature stretch film is often used to package meat, cheese, poultry eggs and other foods requiring high barrier packaging. Its excellent barrier properties can effectively prevent the infiltration of oxygen and moisture, extend the freshness and shelf life of food.

Pharmaceutical industry: Pharmaceutical products have extremely strict requirements for packaging, and the high barrier property and chemical stability of high and low temperature stretch film make it an ideal choice for pharmaceutical packaging. It can not only protect the drug from external contamination, but also ensure the stability of the drug during the effective period.

Chemical industry: In the packaging of chemical products, the strong barrier properties of high and low temperature stretch film can prevent the volatilization and leakage of chemicals, ensuring the safety of transportation and storage processes. At the same time, it also has good corrosion resistance and is suitable for the packaging needs of various chemicals.

Electronic products: Electronic products have high requirements for moisture and dust protection, and the excellent performance of high and low temperature stretch film can provide comprehensive protection to ensure the safety and reliability of electronic products during transportation and storage.

4. FAQ

What is the minimum temperature that high and low temperature tensile film can withstand?

Different types of high and low temperature tensile film can withstand the minimum temperature is different. In general, high-quality high and low temperature tensile films can withstand temperatures of -50 °C or even lower. This mainly depends on its material formula and manufacturing process. In the low temperature environment, the flexibility and tensile properties of the film can still be maintained, and will not become brittle, thus ensuring effective protection of the packaged items.

What about the maximum temperature? How hot can it stand?

The maximum temperature it can withstand is usually 120°C - 150°C. In this temperature range, the structure of the film is stable, and there will be no deformation, melting and other problems. This makes it suitable for packaging scenarios that require high temperature processing, such as high temperature cooking packaging for certain foods or product storage and transportation packaging in high temperature environments.

How does the tensile strength of high and low temperature tensile film change under high and low temperature environment?

In the low temperature environment, the molecular chain activity of the stretched film is weakened, but the tensile strength of the high-quality high and low temperature stretched film will be maintained at a certain level through the special molecular structure design and additives, and will not be significantly reduced. In a high temperature environment, the film may soften to a certain extent, but a good high and low temperature tensile film can still maintain enough tensile strength to prevent the packaging from breaking. Overall, it is designed to control the change in tensile strength within the range of high and low temperatures without affecting the packaging function.

Is its barrier property stable at high and low temperatures?

The barrier properties of gas and water vapor are basically stable at high and low temperatures. At low temperatures, the dense structure of the film will not be destroyed, and it can still effectively block the penetration of gases and water vapor such as oxygen and carbon dioxide. At high temperatures, although the molecular movement is intensified, the special composite structure and material properties of the film can ensure the function of the barrier layer, thus ensuring the freshness and stability of the packaged item.

What about in electronics? What are the special application requirements?

In the electronics industry, high and low temperature stretch film can be used for the packaging of electronic components. Electronic components may experience different temperature environments during storage and transportation. The high and low temperature stretch film protects components from moisture, static electricity and physical damage in the range of -40 °C to 85°C, which is a common temperature range in the electronics industry, ensuring that their performance is not affected by temperature changes.

Is high and low temperature stretch film suitable for pharmaceutical industry?

Yes, for the pharmaceutical industry. During the refrigerated transport of medicines (such as the transport of vaccines, where temperatures can be as low as -20 °C), it can provide good protection against the effects of temperature and the external environment. At the same time, for some drugs that need to be stored in a high temperature environment (such as some special external drugs in a hot environment), it can also ensure the stability of the drug.

How is the high and low temperature stretch film produced?

It is usually produced by multi-layer co-extrusion technology. The polymer materials with different characteristics are co-extruded into films by extruder according to the designed order and thickness. In the production process, the parameters such as thickness, temperature and extrusion speed of each layer are precisely controlled to ensure that the high and low temperature properties, barrier properties and tensile properties of the film meet the expected requirements.

How to judge the quality of high and low temperature stretch film?

It can be judged from several aspects. The first is the tensile property, the tensile strength and elongation at break at high and low temperatures are tested by tensile test. The second is the barrier performance test, testing its barrier ability to gas and water vapor. In addition, observe whether the appearance of the film is smooth, uniform, without defects and holes. Simulated packaging tests in high and low temperature environments to check the integrity of the packaging and the protection effect of the packaged items are also important methods to judge the quality.
