Blister packaging box manufacturers production process

2018-11-07

Mold making and processing: According to the requirements or sample specifications, firstly, the plastic mold is made. Under normal conditions, the plastic packaging mold is made by gypsum, but the wood carving and metal carving products are also used as the mold. After the plaster mold is made, Let it dry naturally or completely, and then use the 1-2 mm drill to drill many small holes in the low concave of the product packaging without affecting the surface of the product. If it is a box or the like, It is necessary to drill some small holes in the periphery of the four sides so that the air can be extracted when the plastic is produced. After the hole is drilled, the plaster mold must be hardened. The hardening method is to soak with the concentrated liquid of the concentrated alum. dry.

If the fruit turns yellow, the content of vitamin C will decrease, and it can be seen that respiration is the main factor affecting the freshness of vegetables and fruits. In addition, the corrosive action of pathogenic microorganisms is another factor that causes the decrease in the freshness of vegetables. In particular, the content of vitamin C is 7-10 times higher than that of apples and grapes. The content of malic acid, citric acid, vitamin B1, vitamin B2, and carotene, calcium, phosphorus and iron is also three to four times higher than that of apples, pears and grapes. Respiration can cause internal component consumption, softening of meat, and reduced nutritional value; ethylene gas can promote the aging of vegetables and fruits, and accelerate the respiration; the moisture content of vegetables and fruits is as high as 85% to 95%, if the water loss reaches 5%, The appearance will be ruined and the price of the commodity will be lowered. Use plastic boxes to reduce the effects of these respirations.

The plastic box is blister-packed and finished, and the produced products are trimmed and finished as finished products, which can be sold after being packaged. The softened plastic sheet is placed in a vacuum chamber together with the wooden cabinet, and the suction switch is activated to suck the vacuum chamber air. After the plastic sheet is cooled, the same concave package or process mold as the mold is obtained. Blister packaging also aims to display and protect products. The packaged products are mostly small commodities, which can be placed or hung on the shelves of supermarkets, so that your products can be well displayed in front of customers and thus increase product sales.
