How to distinguish the quality and safety of blister box products

2023-09-18

Blister box can improve the price and image of the product itself, and at the same time, it also plays a role in shaping and disseminating, which has a significant impact on the brand image and popularity of the enterprise. Blister box also aims to display and protect products. Most of the packaged products are small commodities, which can be placed or hung on the shelves of supermarkets, so that your products can be perfectly displayed in front of customers to promote product sales; blister box to separate, shockproof, foil for the purpose of packaging products are mostly electronic, IT, industrial parts, toys, stationery, food, handicrafts and cosmetics, etc., can be packaged many and small products, so that the product is more overall beautiful. PET hard sheet has good toughness, high transparency, easy combustion, does not produce harmful gas when burning, belongs to environmental protection material, but the price is high, suitable for high-grade blister products, blister shells in European and American countries generally require PET hard sheet, but it is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on PET surface, which is PETG hard sheet, but the price is higher. The materials used for thick plates are mainly: ABS, acrylic (organic glass),PS,PC,PVC and other blister packaging.

First of all, blister packaging materials are characterized by light weight, good toughness, for the need for long-distance transport of goods, can play a role in reducing transport weight, easy to transport, which is other packaging materials can not be compared. Secondly, blister packaging materials have very good barrier properties and permeability. In plastic packaging, there are gas-resistant packaging, moisture-proof packaging, waterproof packaging, and various fresh-keeping packaging for fruit food. These are all plastic packaging. To ensure the breathing of fresh ingredients and extend the packaging. Again, the optical performance of the blister packaging is very good, because the blister packaging material can be transparent, so when it is made into a packaging container, the items inside can be seen clearly, this indirect eye-catching effect is very good. Special mention here is that blister packaging materials are environmentally friendly and hygienic. Compared with those pure polymer resins, blister packaging can be said to be non-toxic, so if we want to pack food, we can safely use regular blister packaging materials.

Disadvantages of blister packaging materials: for individual resin monomers, especially monomer polyethylene, when they are used in plastic packaging materials, if the content is too high, that is, when they reach a certain concentration, they are easily absorbed by the food in the package, thus causing certain harm to the human body. This part of plastic packaging materials is not suitable for food packaging. In addition, blister packaging materials are not as good as other hard materials in terms of strength and hardness, and have disadvantages such as poor heat resistance and easy aging of materials. The production principle of blister box packaging is mainly to form a flat plastic hard sheet material into a plastic box shape by vacuum suction and cooling after high temperature heating. Vacuum adsorption on the surface of the mold, after cooling molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.
