Anti-fogging agent
Anti-fogging agent, also known as anti-fog drops or drops. PVC agricultural film can be prevented to reduce the occurrence of water droplets in the transparent material. Mainly surfactants, esters such as xylitol, sorbitol monopalmitate, or lauric acid monoglycerides hard resin and the like. Plastic packaging materials, plastic packaging material permeability properties
Factors affecting the barrier properties of plastic packaging materials, molecular polarity 1. 2. 3. molecular crystalline molecular hydrophilic molecular orientation 4. 5. Ambient temperature
Improve the barrier properties of plastic packaging materials composite modification method
2. Add the modified additives
3. Surface Coating Modification
(1) vacuum aluminum
(2) vacuum plating oxide (3) coated with amorphous carbon (4) 4. The coated barrier resin modified chemical treatment
Health plastic packet transfer material hygienic hygiene 2. 1. plasticizer stabilizer
3. The health of colorants and inks hygiene 4. Other plastic additives other properties
1. Plastic transparency printability 2. 3. 4. antistatic heat sealability
Flexible packaging and plastic molding
Category 1. singlemode plastic flexible packaging materials 2. Composite material is extruded
In the processing of plastic packaging products, usually the first solid plastic resin into a melt by a suitable method, then it will melt molding such a certain way, to the required manufacturing plastic packaging products. This process can be accomplished in many devices, one of which is an extrusion process, the extrusion process is mainly used to produce films, sheets, and extrusion blow molding bottles and plastic packaging products, equipment used is a plastic extruder.
