Green plastic packaging has become an inevitable trend

Today, when people are paying more and more attention to food safety and physical health, talking about "plastic" discoloration has become a phenomenon that has gradually appeared in the packaging industry. In fact, as the backbone of the packaging industry, plastic materials have been loved and "reused" by all kinds of companies since their birth, and the future development prospects of this market are also very broad. However, based on the inevitable trend of the increasingly mature concept of green environmental protection, green packaging should become the main development direction of plastic packaging in the future.

The most complete analysis of heat sealing failures of flexible packaging composite bags

Commonly used heat-sealing materials for composite packaging include CEP, LPPE, CPP, OPP, EVA, hot melt adhesives and other ionic resin co-extruded or blended modified films. The thickness of the heat-sealing layer material generally floats between 20-80μm. In special cases, there are 100-200μm, the same heat-sealing material, the heat-sealing strength increases with the increase of the heat-sealing thickness. For example, the heat-sealing strength of cooking bags is generally required to reach 40-50 Newtons, so the heat-sealing thickness should be above 60-80μm. The temperature is involved in the process of heat-sealing bag making, and how much temperature is controlled is displayed by a temperature meter. In the process of heat-sealing composite bag processing, the more precise the temperature gauge is, the better, and the error range and setting value should not exceed ±5℃. The heat sealing temperature has the most direct influence on the heat sealing strength, and the melting temperature of various materials directly determines the minimum heat sealing temperature of the composite bag.

How to tell whether plastic bags meet food standards?

The first thing to look at is whether there is a "food use" mark on the appearance of the plastic bag. Usually this logo should be on the front of the packaging bag, a more eye-catching position. Secondly, look at the color. Generally speaking, colored plastic bags mostly use recycled materials from waste plastics and cannot be used for food. For example, some black plastic bags used to hold fish, shrimp and other aquatic products or meat in some vegetable markets were originally used to hold garbage, and consumers should avoid using them. It depends on the presence or absence of impurities in the plastic bag. Put the plastic bag in the sun or light to see if there are black spots and openings. Plastic bags with impurities must use waste plastics as raw materials.
