Prime quality butter packaging aluminium foil

Haomei prime quality butter packaging aluminium foils 8011 has thickness of 0.006-0.018 (mm), bursting resistance: 100 (%), stiffness: 80, opacity: 100 (%). The butter aluminium foil is food grade and can be contact with butter immediately safe to maintain its taste and quality.

With the development of technology, metal is gradually involved in the research and development of packaging materials, especially the use of aluminum foil. Butter aluminum foil is soft in texture and good in ductility, with excellent moisture-proof, air-tight, oil-proof, light-blocking, non-toxic and other advantages, which can be combined with traditional packaging materials to improve the composite properties.

The packaging of butter should be mainly based on oxygen barrier and light-blocking, and the basic functions of oil-proof and sealing should be provided. Regardless of the automatic oxidation of the fat or the oxidation of the light, oxygen is a necessary condition. Since it is impossible to prevent the penetration of oxygen, reducing the rate of oxygen permeation into the butter packaging becomes a top priority. Therefore, the use of aluminum foil packaging materials with high barrier properties to oxygen can effectively solve this problem. Light, such as sunlight and incandescent light, can cause photooxidation of butter lipids, so packaging materials with good shading can greatly slow down the process. At the same time, the butter packaging aluminium foils should also have certain moisture resistance and heat insulation, weakening the catalysis of moisture and high temperature on the oxidation of butter oil.
