Food Blister Packaging The technological requirements

Blister products help items have the effect of beautification, also can protect the goods and the process of transportation, also have the effect of stability, more important is to improve the level and value of the goods, as the life of people than ever before to lead a good life. Consumption also gradually became everybody to do every day, in the process of consumption in order to better meet customers thought the goods, and the pursuit of the appearance, blister box packing use benefits can increase items, beautification, the scale, the value and importance of the item In the transformation for sales of the item.

Process requirements and standards of food blister packaging box

As the name suggests, food is used for storing food. In order to ensure the quality of food and avoid the quality of food stored in the box, the food absorbing-packaging boxes must meet the relevant standards when making. The following is to introduce the process requirements of food plastic packaging box.

1. It can only produce the products with more uniform wall thickness, (the lower corners are slightly thinner), and the plastic products can not be made in thickness

2. The wall thickness of the moulded moulding is generally within 1 to 2mm or thinner (the most commonly used thickness is 0.15 to 0.25mm for small packaging)

3. The tensile degree of the moulded products is limited, and the diameter of plastic container is less than 1. In extreme cases, it must not exceed 1.5

4. The size precision of the suction molding is poor, and its relative error is generally more than one percent.

A, PVC sheet high toughness, not easy combustion, the combustion can be induced in chlorine gas, a certain effects on the environment, PVC heat sealing, can use sealing side of sealing machine and high frequency, is the main material in the manufacture of the transparent blister packaging products. PVC sheet is a kind of widely used and popular material, PVC film can be divided into two kinds of environmental protection and not environmental protection, can be made into a transparent, color, antistatic, gold-plated, flocking, etc all kinds of blister packaging products, the main characteristics of high transparency, good surface luster, crystal points less, small water lines, wide application, strong shock resistance, and easy to forming, the products are widely used in toys, food, electronics, medicine, electrical appliances, gifts, cosmetics, stationery, and other products packaging.

Second, PS hard film density is low, malleability is poor, easy to burn, can produce styrene gas (belonging to harmful gas), so it is commonly used to produce plastic tray for industrial use. PS plate is a new kind of environmental protection packaging materials developed in recent years, with its good thermal formability, good environmental protection performance and health performance, widely used in medicine, food, toys, electronic.

3. Good toughness of PET hard film is a new material developed in recent years. With its good toughness, high strength, high transparency, and can be recycling use, easy to burn, burns does not produce harmful gases, belongs to the environmental protection material and clamp down on PVC, but the price is high. Suitable for high-grade blister products, blister blister of European and American countries generally require the use of PET materials, but its heat high melting point, bring great difficulty to high frequency packaging, in order to solve this problem, people on the PET surface composite layer of PVC film, named PETG, but the price higher. Mainly used in electronic, food, toy, color box window, collar, shoe packaging, etc.
