The molecular chain of cellophane has a wonderful micro-breathability, which allows the commodity to breathe like an egg through the micropores on the egg skin, which is very beneficial to the preservation and preservation activity of the commodity; The organic solvent has strong resistance; does not generate static electricity, and does not absorb dust; because it is made of natural fibers, it can absorb water in the garbage and be decomposed, so as not to cause environmental pollution. Widely used in commodity lining paper and decorative packaging paper. Its transparency allows people to see the goods inside at a glance, and it has the properties of moisture-proof, water-proof, micro-breathable, heat-sealable, etc., which plays a good role in protecting the goods. Compared with ordinary plastic film, it has the advantages of no static electricity, dustproof, good kink and so on. Cellophane is available in white, colored, etc. Can be used as a semi-permeable membrane.
Cellophane is regenerated cellulose, and its molecular clusters have a wonderful air permeability, which is very beneficial to the preservation of commodities. It is not fire-resistant but heat-resistant, can be deformed at a high temperature of 190 ° C, and can be high-temperature sterilized with food in food packaging. In addition, since the raw material of cellophane is derived from nature, it has strong decomposability.
After using it to package items, it can prevent rust, moisture and pollution. However, cellophane also has disadvantages: high longitudinal strength, low lateral strength, poor tearing degree, and it will break as soon as a slight crack is torn. Cellophane is also hydrophilic, so it can absorb water, and it often sticks when exposed to water. The characteristics of cellophane are high transparency, strong gloss, and especially bright color after printing pictures and texts, which cannot be achieved by plastic films; good printability, no need to go through any treatment before printing, and cellophane also has antistatic properties, which is not easy to achieve. It absorbs dust and avoids the occurrence of printing failures such as sticking and dusting of graphics and text, but it has poor moisture resistance, and the film is easily deformed by the influence of temperature and humidity, which makes it difficult to register graphics and text during printing.
