What is the meaning of plastic sheet?

by:SYJ     2020-10-31

plastic sheet refers to the plastic raw materials ( Particles) In the plastic extruder or plastic calender heating, melting, extrusion or rolling out thickness at 0. 1 - 2. 0 mm plastic coil.

this kind of material are mainly PVC, PET, PS, PP, ABS, etc.

according to different processing, can be divided into: extrusion sheet and rolling sheet.

according to different purposes, can be divided into: food grade and medical grade and regular grade.

whether there is material mixed with back, depending on the materials can be divided into: new materials, materials level ( A grade) , secondary materials ( B) 。

sheet is mainly used in blister and plastic printing industry. Wide range of USES. Application range

1, the construction, such as: the window wall, sound insulation, light shade, solar collector, a telephone booth.

2, advertising display, such as: light boxes, signs, signs, display racks, spherical cap, guideposts.

3, industrial products, such as instrument panel, machine shield, flow meter, auto tail lamp housing.

4, lighting, such as: solar chimney, environmental purification equipment with various shapes of chimney.

5, civilian class, such as: sanitary equipment, dresser, picture frames, items, gifts, souvenirs, cool chair to sit back, candy boxes, ratten, food cover, high-grade aquatic animals.

common sheet

a: PVC, PET, PP, PS, and on this basis the flocking sheet, gold-plated sheet and anti-static sheet. PVC:

the most common blister material, soft, strong toughness, good plasticity, but make it transparent and a variety of colors, the commonly used transparent PVC packaging electronics, cosmetics, toys, gifts and other products.

宠物( A - PET) : hard, good toughness, high strength, surface brightness, environmental non-toxic, transparent and a variety of color sheet. Defect is PET high frequency thermal bonding are difficult, the price is more expensive than PVC, this material has often been asked customers high-grade and environmentally friendly products to replace PVC

PS: density is small, Light) , environmental non-toxic, plasticity is very good, poor ductile brittle, not make it bright material, therefore can only make the collet type blister, because of its easy to crack, should not be such a blister recycling

PP: material of special soft, good toughness and environmental protection non-toxic, high temperature resistant, has often been made catering utensils or other high temperature resistant products packaging; But its poor plasticity, processing is difficult, the surface gloss, color will be shallow and processing.

宠物- G: physical properties with A minus PET is similar, but can be high frequency thermal bonding, its price is A - PET is also 80% more expensive.
