The so-called blister tray, is the use of plastic made of pallets, pallets, a lot of grooves, the product to the grooves, you can play a good role in the protection and landscaping, so as to facilitate the transportation and handling. Of course, there are also used in the transportation industry tray packaging, in addition to plastic trays, there are paper trays, wooden trays and so on. Blister tray in our life is also used more widely, such as cake store inside a variety of small cakes, fruit store inside the packaged fruit, packaged meals, etc., are the use of blister trays to load. Today we mainly understand the blister tray common materials and their respective characteristics.
Blister tray - blister tray material
1, PVC material
This material has a high toughness, is not easy to burn, combustion produces chlorine gas, a certain impact on the environment, PVC is easy to heat sealing, can be used to sealing machine and high-frequency sealing, is the main raw material for the production of transparent blister products.
Features: high transparency, good surface gloss, less crystal points, small water lines, wide range of uses, impact resistance, and easy to mold.
Applications: widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products packaging.
2, PET material
This material has good toughness and is a new material developed in recent years. With its excellent toughness, high strength, high transparency, as well as recyclable, easy to burn, burning does not produce harmful gases, is an environmentally friendly materials and gradually outlawed PVC, but the price is high. Suitable for high-grade blister products, Europe and the United States, the general requirements of the blister PET material, but its thermal melting point is high, to the high-frequency encapsulation brings great difficulties.
Features:
Good toughness, high strength, high transparency, as well as recyclable and reusable, easy to burn, combustion does not produce harmful gases
Applications:
Generally this material is environmentally friendly and healthy, and is not easy to produce toxic substances, and thus is widely used in food blister trays, pastry boxes, cake boxes, and other products blister trays. Where direct contact with food will generally use the use of this material, he has a non-toxic, environmentally friendly and healthy characteristics.
3, PS material
This material is low density, poor toughness, easy to burn, combustion will produce styrene gas (a harmful gas), so generally used to produce a variety of industrial blister trays. PS sheet is now a few years the development of a new type of environmentally friendly packaging materials, by virtue of its excellent thermoforming properties, good environmental protection and hygiene performance.
Features: low density, poor toughness, easy to burn.
Applications: Widely used in medicine, food, toys, electronics.
4, PETG material
It is in order to solve the PET material hot melting point is higher this problem, people in the PET surface composite on a layer of PVC film, named PETG, but the price is a little higher.
Features:
a, excellent transparency and finish, good display effect.
b, excellent surface decorative properties, can be printed without surface treatment, easy to press patterns, easy to metal treatment (vacuum plated metal layer)
c, has good mechanical strength.
d, oxygen and water vapor barrier performance is good.
e, good chemical resistance, can withstand a variety of chemical substances.
f, non-toxic, hygienic and reliable performance, can be used for food, drugs and medical equipment packaging, and can be Y-ray [span] on the items it packages sterilization.
g, good adaptability to environmental protection, can be economically and conveniently recycled; incineration of its waste, does not produce environmentally harmful substances. This kind of sheet is considered to be an ideal packaging material in line with (ROSH) environmental protection requirements.
Applications: Mainly used in electronics, food, toys, color box window, collar tray, footwear packaging and so on.
5, PP material
This material is made of polypropylene resin as the main raw material, adding a variety of process masterbatch, toughening agent and brightener, after mixing, plasticizing extrusion, three-roller calendaring, cooling, hauling and winding and other processes.
Features: PP blister has: environmental protection, beautiful, can be silk-screen, Ko printing, hot stamping, high temperature, low temperature resistance, high transparency, resistance to flexing easy to fold, the product meets the food test standards (can also not be required), microwaveable.
Advantages: PP sheet has the characteristics of non-toxic, odorless, hygienic, high mechanical strength and good barrier, etc. It can be used for packaging in industry, agriculture, fruit and other industries. The surface of the tray made of PP anti-slip sheet processing is smooth and beautiful, which is popular among users.
Disadvantages: low dimensional accuracy, lack of rigidity, poor weather resistance, easy to produce "copper", it has a post-shrinkage phenomenon, after demolding, easy to aging, brittle, easy to deformation.
Applications: PP sheet is also suitable for the packaging of high cold-resistant frozen food, such as ice cream boxes, dumpling boxes, dumpling boxes and so on.
On the blister tray material, through the above detailed introduction, we learned that the common material blister tray PVC material, PET material, PETG material, PP material, PS material, and the above also on the characteristics of the relevant material, advantages and disadvantages, uses and so on to give us a detailed introduction, I hope that friends want to understand, you can carefully read and collect this article. It can be said that different materials of the blister tray, corresponding to the use is different, so we need to selectively buy it if the family has the need.
