Plastic sucker-plastic sucker material
1 and PVC material
This material has high toughness and is not easy to burn. Chlorine gas will be produced during combustion, which has a certain impact on the environment. PVC is easy to heat seal, and can be sealed by sealing machine and high frequency. It is the main raw material for producing transparent plastic products.
Features: High transparency, good surface gloss, less crystallizing point, small waterline, wide application, strong impact resistance and easy molding.
Scope of application: It is widely used in the packaging of toys, food, electronic products, medicines, electrical appliances, gifts, cosmetics, stationery and other products.
2, PET material
This kind of material has good toughness and is a new material developed in recent years. PVC has been gradually banned as an environmental protection material because of its excellent toughness, high strength, high transparency, recyclability, easy combustion and no harmful gas when burning, but its price is higher. Suitable for high-grade plastic products. Plastic blister housings in Europe and America generally require PET material, but its high melting point brings great difficulties to high-frequency packaging.
Features:
Good toughness, high strength, high transparency, recyclable, easy to burn, and no harmful gas is generated when burning.
Scope of application:
Generally speaking, this material is environmentally friendly and healthy, and it is not easy to produce toxic substances, so it is widely used in food plastic trays, cake boxes, cake boxes and other products. Anyone who comes into direct contact with food will generally use this material, which has the characteristics of non-toxicity, environmental protection and health.
3, PS material
This material has low density, poor toughness and is easy to burn. Styrene gas (a harmful gas) will be produced when burning, so it is generally used to produce various industrial plastic trays. PS sheet is a new type of environmental protection packaging material developed in recent years. With its excellent thermoformability, good environmental protection performance and sanitary performance.
Features: low density, poor toughness, easy to burn.
Uses: Widely used in medicine, food, toys and electronic products.
4. PETG materials
In order to solve the problem of high thermal melting point of PET, people compound a layer of PVC film on the surface of PET, named PETG, but the price is higher.
Features:
A, excellent transparency and smoothness, and good display effect.
B, excellent surface decoration performance, printing without surface treatment, easy embossing and metal treatment (vacuum metal plating).
C, with good mechanical strength.
It has good barrier performance to oxygen and water vapor.
E, good chemical resistance, can withstand the erosion of various chemicals.
F, non-toxic, reliable hygiene performance, can be used to package food, medicine and medical devices, and can be used to sterilize the packaged items with gamma rays [span].
G, good environmental adaptability, and can be recycled economically and conveniently; When burning garbage, it will not produce harmful substances that harm the environment. This kind of sheet is considered as an ideal packaging material meeting the requirements of environmental protection (ROSH).
Uses: mainly used for electronics, food, toys, color box windows, collars, footwear packaging, etc.
5, PP material
The material is made of polypropylene resin as the main raw material, and various process color masterbatch, toughening agent and brightening agent are added, and then mixed, plasticized and extruded, three-roll calendered, cooled, drawn and wound.
Features: PP plastic absorption has: environmental protection, beauty, screen printing, offset printing, bronzing, high temperature resistance, low temperature resistance, high transparency, bending resistance, easy folding, products meeting (or not meeting) food testing standards, and microwave.
Advantages: PP sheet is non-toxic, tasteless, hygienic, high in mechanical strength and good in barrier property, and can be used for packaging in industries such as industry, agriculture and fruit. The surface of PP anti-slip pallet is smooth and beautiful, which is well received by users.
Disadvantages: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper loss", shrinkage phenomenon, easy to age, brittle and deform after demoulding.
Usage: PP sheet is also suitable for packaging high cold-resistant frozen foods, such as ice cream boxes, jiaozi boxes, dumpling boxes, etc.
With regard to the materials of plastic tray, through the above detailed introduction, we know that the common materials of plastic tray are PVC, PET, PETG, PP, PS, and their respective characteristics, advantages and disadvantages, uses, etc. The detailed introduction of relevant information is also above. I hope friends who want to know can carefully read and collect this article. It can be said that plastic trays made of different materials have different uses, so you need to buy them selectively if you have demand at home.
