مقدمة رئيسية

Anti-fog PET plastic sheet is a new type of environmentally friendly packaging material with the characteristics of high transparency, double-sided anti-fog, folding resistance, chemical corrosion resistance, and low-temperature brittleness resistance. It is widely used in food, electronic devices, medical devices and other fields.

ميزة

• Long-lasting anti-fog effect: The anti-fog effect of anti-fog PET plastic sheet can last for months or even years without frequent replacement.
• Environmental protection: PET material is a recyclable material, and anti-fog PET plastic sheet meets environmental protection requirements.
• High safety: PET material has good biocompatibility, and anti-fog PET plastic sheet can directly contact food, which is safe and reliable.

Advantage

• High transparency: PET material itself has excellent transparency. Anti-fog PET plastic sheet has anti-fog function on the basis of maintaining high transparency, which can clearly show the appearance of the product.
• Double-sided anti-fog: Anti-fog PET plastic sheet is treated with special technology, which can effectively prevent water vapor from condensing into droplets on the surface of the sheet, thereby achieving the effect of double-sided anti-fog.
• Folding resistance: PET material has good toughness, anti-fog PET plastic sheet is not easy to break, and it is convenient to process into various shapes.
• Chemical corrosion resistance: PET material has good chemical corrosion resistance and can withstand the erosion of various chemical substances.
• Low-temperature brittleness resistance: PET material has good low-temperature resistance, and anti-fog PET plastic sheet is not easy to brittle in low-temperature environment.

Anti-fog PET plastic sheet production process

The production process of anti-fog PET plastic sheet mainly includes the following steps:

Raw material preparation: Dry, mix, color and other pre-treatments of PET raw materials.

Extrusion molding: The prepared PET raw materials are melted and plasticized at high temperature, and then extruded into PET sheets through a mold.

Surface treatment: The surface of the PET sheet is hydrophilically modified or nano-coated.

Cooling and shaping: The treated PET sheet is cooled and shaped.

Cutting and packaging: The PET sheet is cut into the required size and packaged for shipment.

Application of anti-fog PET plastic sheet

Food packaging: Anti-fog PET plastic sheet can be used to make food packaging boxes, trays, partitions, etc., which can effectively prevent food from getting damp and deteriorating and extend the shelf life.

Electronic device packaging: Anti-fog PET plastic sheet can be used to make electronic device packaging boxes, trays, partitions, etc., which can effectively prevent electronic devices from getting damp and damaged.

Medical device packaging: Anti-fog PET plastic sheet can be used to make medical device packaging boxes, trays, partitions, etc., which can effectively prevent medical devices from getting damp and contaminated.

Other applications: Anti-fog PET plastic sheet can also be used to make goggles, masks, dust covers, etc.

How to make PET plastic sheet anti-fog

The anti-fog principles of anti-fog PET plastic sheet are mainly the following two:

• Hydrophilic modification: hydrophilic modification is performed on the surface of PET material to make the surface of the material more hydrophilic. Water vapor spreads evenly on the surface of the material to form a thin liquid water film. Light can penetrate the water film, thereby achieving the anti-fog effect.
• Nanotechnology: a layer of nanofilm is coated on the surface of PET material. The pore size of the nanofilm is smaller than that of water vapor molecules, but larger than that of air molecules. Water vapor molecules cannot enter the nanopore size, while air molecules can pass freely, thereby achieving the anti-fog effect.
• Additives: anti-fog agents such as polyethylene glycol and glycerol are usually added to anti-fog PET plastic sheets, which can absorb water vapor and prevent water mist from condensing.

The anti-fog effect of anti-fog PET plastic sheet mainly depends on the type and content of surface treatment and additives.

Surface treatment: Different surface treatment methods have different anti-fog effects. For example, the anti-fog effect of hydrophilic treatment is better, but the wear resistance is poor; the anti-fog effect of nanotechnology treatment is long-lasting, but the cost is higher.

Additives: Different anti-fog agents have different anti-fog effects. For example, polyethylene glycol has a better anti-fog effect, but poor high temperature resistance; glycerol has better high temperature resistance, but the anti-fog effect is slightly inferior to polyethylene glycol.
