Properties o Wuhan Modern machinery co .ltdfAcetate Film,
The properties as a packaging material are as follows:
(1) Mechanical properties One of the biggest characteristics of cellulose acetate is its large flexural modulus. It has a good surname and strong resilience. This is due to the nature of the cellulose molecular chains that make up the macromolecular skeleton of cellulose acetate. It remains unchanged even at high temperatures. This important property makes it adaptable to automatic packaging machinery. www.handern.com breathable membrane equipment
2) Thermal performance Cellulose acetate film has good heat resistance and low temperature resistance. At a temperature of about 140 ° C, its mechanical properties are almost unchanged, and its size changes are small. Therefore, it can be used for packaging and packaging at high temperatures. High temperature treatment, and in addition, the brittle fracture does not occur at the temperature below zero, which can be used at low temperature. Www.handern.com
CTA has good heat resistance but poor heat sealability, while CDA with low melting point can fully meet the requirements. www.handern.com breathable membrane equipment
(3) The moisture permeability of air-permeable cellulose acetate film is larger than that of polyethylene and polyvinylidene chloride films, but smaller than cellophane, which is exactly at the middle value, and has permeability to other gases (oxygen, nitrogen, carbon dioxide, etc.) The characteristics of high rate, compared with other films, its breathability is just right. It plays an important role in the packaging of fresh vegetables and fruits. Because it has moisture permeability, it rarely holds water droplets or condensation on the inside of the film, which is extremely advantageous in maintaining the aesthetics of the packaging.
(4) Optical properties Cellulose acetate film has excellent light transmission and beautiful film surface. It can be used as a photographic film. When it is used as a packaging material, it can clearly see the contents and beautiful design patterns from the outside of the package. Single-sided printing www.handern.com breathable film equipment
The brush can further improve the gloss effect. It can transmit 300mm ultraviolet light, so it has excellent light aging resistance.
(5) Chemical properties Cellulose acetate film has poor resistance to strong alkalis and strong acids, but has excellent oil resistance, oil resistance, and water resistance. In addition, it does not contain light and heat stabilizers, so it can be directly packaged with food. In the United States, it has obtained FDA ( Food and Drug Administration). www.handern.com breathable membrane equipment
In addition, it has excellent printing adaptability, is not easy to generate static electricity, and is easy to eliminate static electricity.
5.3.4 Application of cellulose acetate film
(1) With transparent window box and prefabricated box, use its transparency for transparent window box or prefabricated box, which can mechanically protect the contents inside and can also see the contents of the goods from the outside, especially CTA, its dimensional stability is good, even if the ambient temperature changes, it is very straightforward at all times, no wrinkles and distortions, and the creases are not white and mixed.
turbidity. (2) CDA is mainly used in blister packs and skin packs. It has good transparency and good heat resistance, and can be packaged at a high www.handern.com breathable film equipment
Warm sterilization, used for the packaging of medical supplies, food utensils and other sanitary articles. It can also be compounded with polyethylene and paper.
Materials have been widely used.
(3) Packaging of fresh fruits It is not easy to keep fresh fruits with good color, fragrance and taste during storage. Generally, moisture-proof and gas-proof packaging is helpful for maturity. For this reason, the use of Cellulose acetate films that are permeable to moisture and carbon dioxide are most suitable. The packaging of fruit-filled confections and pastries similarly imposes certain requirements on breathability. Acetate film window packaging can be used.
(4) Composite packaging cellulose acetate can be further compounded with paper, metal foil and other plastics to further improve the excellent gloss, printing adaptability, damage resistance, elastic recovery and other properties of cellulose acetate. If compounded with aluminum foil, It can be changed into a moisture-proof and waterproof film, and it has become a film with excellent packaging functions. Most of these composite films are used for the packaging of antibiotic drugs such as penicillin, dry food, and drinks. www.handern.com breathable membrane equipment
