Locate vacuum molding machine to tell you the advantages and disadvantages of vacuum forming packaging materials

Locate vacuum forming machine to tell you the advantages and disadvantages of vacuum forming packaging materials in our daily life, vacuum forming packaging is widely used in various household goods, merchants in order to attract customers, use a variety of beautiful vacuum forming box to pack goods, such as fruit transparent PP vacuum molding vacuum molding box, food box, vacuum forming trays, meat cooked food vacuum forming trays, vacuum forming last box, vacuum forming trays, fresh vegetables vacuum forming tray, vacuum forming cake bread box, etc. So, vacuum forming packaging has what good? Using vacuum forming packaging and what it's worth noting that, today's gold digital professional consultants to take you to learn about the advantages and disadvantages of all kinds of vacuum forming packaging materials. First of all, the biggest characteristic is vacuum forming packaging material quality is light, can good toughness, the need for long-distance transport of goods, can reduce weight, easy transportation and transport effect, this is not than other packing materials. Second, vacuum forming packaging materials have very good barrier property and permeability, in plastic packaging, there are gas blocking packing, waterproof moisture-proof packaging, packaging, there are various kinds of fruit for food packaging, these are plastic packaging in order to ensure that fresh food of respiration and extension of the packaging.

In addition, the vacuum forming packaging materials in such aspects as strength and hardness than other hard materials, and poor heat resistance and material aging and so on.
