Abstract
The invention discloses a preservative film, and belongs to the technical field of preservative appliances. The preservative film is characterized by comprising, by mass, 35-60% of polyethylene resin, 2-8% of light calcium carbonate, 0.1-1.5% of sodium alginate, 0.5-3% of chitosan, 5-25% of casein, 15-35% of Arabic gum, 0.05-1% of anion antibacterial agents, 0.1-15% of epoxidized soybean oil and the balance beeswax. The preservative film has the advantages that the traditional preservative film only can preserve one type of food and is single in function, while the preservative film can preserve different types of food, is convenient in use and can be reused.
Description
Technical fieldThe present invention relates to a kind of preservative film, belong to fresh-keeping apparatus technical field.
Background technologyPreservative film is the plastic packing product of the class fresh-keeping foodstuff commonly used of people, and in people's daily life now, a lot of places all be unable to do without it, such as: the food in microwave oven heating can be used, and storing food can be used equally in refrigerator.Most preservative films of selling in the market are all take the ethene masterbatch as starting material, different sorts according to the ethene masterbatch, preservative film can be divided into three major types: the first is polyethylene, be called for short PE, this material is mainly used in the packing of food, this film that the fruit that we buy usually, vegetables are used, be included in the supermarket purchase the work in-process of returning all use be this material; The second is polyvinyl chloride, is called for short PVC, and this material also can be used for food product pack, but it has certain impact to the security of human body; The third is polyvinylidene dichloride, is called for short PVDC, is mainly used in the packing of the products such as some prepared food, ham.From physical angle, preservative film has oxygen-permeable and the Water Vapour Permeability of appropriateness, regulates by oxygen content and moisture content around fresh-keeping product, intercepts koniology, thereby extends the freshness date of food.Traditional preservative film need to be selected different types of preservative film according to the kind of different foods, so just causes a kind of preservative film to be merely able to a group food is carried out Preservation Treatment, function singleness.
