Food is one of the indispensable existence of human survival. Without food, human life will not continue. In recent years, with the improvement of people's living standards, people's requirements for food packaging have also increased, especially in the packaging materials of food. Let's take a brief look at six emerging food packaging materials.
1. Corn plastic packaging materials. American researchers have developed a corn plastic packaging material that is easy to differentiate. This packaging material is made by incorporating corn starch into polyethylene. It is suitable for the manufacture of food packaging integrated packaging bags. The packaging material dissolves quickly in water and prevents contamination.
2. Wood powder plastic packaging materials. Japanese scientists and technicians have researched and manufactured a wood powder plastic packaging material from pine wood. This wood powder plastic packaging material is extremely resistant to heat and can be used to manufacture temperature-resistant packaging bags that can be differentiated by living organisms.
3. Canola plastic packaging materials. Rapeseed plastic packaging materials are developed in the UK. This kind of plastic processing packaging material or food fast food packaging material can differentiate itself after being discarded, leaving no pollution residue.
4. Soy plastic packaging materials. Proteins made from soybeans in the United States produce plastic-like food packaging materials that can replace petroleum-based plastics. This manufacturing technique is used in food packaging to provide a good flexibility, strength and moisture resistance.
5. Wheat plastic packaging materials. This is a translucent plastic plastic film made from wheat flour that can be differentiated by microorganisms.
6. Chlorophyll plastic packaging materials. A plastic film "stained" by chlorophyll invented by German scientists. The technically treated film, which is used to package food, can be used to “catch out†the light that causes the food to decay, greatly extending the shelf life of the food.
