Q:What material should be used for transparent packing bags? How many cents do you want?
PVC, English referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxide, such as azo compound initiator; or in light, under the action of heat polymerization by free radical reaction mechanism of polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.
Q:How many kinds of packing bags are there in the packaged foods?
You ask about food plastic packaging, it is generally packaged with composite bags, composite materials, polyethylene (PE), polypropylene, nylon, polyester. These are the main membranes. The film is made of stretch film and blow film. Dry frozen goods, generally cooked with PET/PE., such as high temperature, it is generally nylon, composite CPP, or other composite, many kinds. I am in Dongguan, Humen, food packaging, such as alcoholic peanuts, bags, red dates bags, mask packaging bags, washing powder bags, areca bags, milk powder bags, small fish bags.
Q:What is the difference between LDPE and PE-LD in a package?
LDPE is low density polyethylene, and PE-LD should be low density polyethylene. Because according to the PE classification, LDPE (low density polyethylene), MDPE (medium density polyethylene), HDPE (high density polyethylene), VLDPE (low density polyethylene), LLDPE (linear low density polyethylene (mPE), metallocene PE). See, "LD" means "low density".
Q:Why are some teas not vacuum packed?
Feng Xing packaging machinery factory experts explained that the main role of vacuum packaging machine is oxygen, moisture, high temperature fermentation, etc., in order to prevent the deterioration of tea. The principle is relatively simple, which is conducive to vacuum packaging machine to remove the air in the packaging bag, and then sealed, so that tea in a vacuum under the state, and absolutely isolated from the outside world.
Q:What is bread packing? Polyethylene film, waterproof cellophane, etc.
More importantly, the use of aluminum foil / composite or polyethylene composite or aluminum foil / polyethylene composite material. Although this type of packaging is opaque, it protects against loss of vitamin B1 in bread.
Q:Is the packet in the food package a reducing agent or an oxidizing agent?
Take active ferric antioxidants as an example;Due to the activity of iron is extremely fine powder, high surface area, the rate of reaction with oxygen is faster. Reduced iron powder. In general, the reaction equation is 4Fe+3O2+6H2O=4Fe (OH) 3, and iron corrosion reactions may also occur.Followed by iron powder particles will adsorption of these smaller food packaging bags in water, the water, in part from within the food, in part from nature. After absorbing most of the excess water, the relative humidity in the food package can be kept constant, which plays a very important role in controlling microbial pollution.
Q:What are the characteristics of a good package?
According to the statistics of the foreign trade department, because of the backward packaging of export commodities, China has reduced the foreign exchange earnings by at least 10% per year. This shows that the good packaging design for the importance of national economic development.
Q:The shelf life of the package usually takes several forms
Milk is extremely nutritious and therefore very perishable. In order to keep fresh and safe to consumers during circulation, the milk must be thoroughly sterilized and securely packaged. The sterilization method, compared with traditional pasteurization, the ultra high temperature sterilization (Ultra High, Temperature, UHT), can greatly reduce the milk color, flavor and nutritional value of the loss, and become the best and fastest way to the development of processing.
Q:What material is the surface of the packing bag such as instant noodles, pickled mustard tuber, small bread and so on? Why should we add this layer?
First, it is easy to heat seal, otherwise only aluminum foil can not be sealed;Two, high barrier plastic film preservation effect is also very good, can increase its number of layers, reduce aluminum foil thickness, thereby reducing costs
Q:What ink is the food packing bag printed on?
Because of this, benzene soluble chlorinated polypropylene ink has been gradually eliminated, and in Europe and other developed countries have gradually introduced or banned the use of benzene soluble chlorinated polypropylene ink laws and regulations.
