Q: Is the packet in the food package a reducing agent or an oxidizing agent?: In many food packages, the Producers place a packet of antioxidants and note the words "antioxidants, not edible". Its function is to absorb oxygen in the food bag, so that the oxygen level in the bag is controlled at a very low level, to prevent the proliferation of microorganisms in the bag. Because the growth and division of microorganisms require the participation of oxygen, the spores and hyphae of microorganisms are strongly inhibited under anoxic conditions. Thereby, the food in the bag is preserved, and the probability of microbial contamination is reduced.

Q: What are the advantages and disadvantages of OPP and CPP membranes? What kind of bags are they used for?: (feature film, also called special film) potential uses include: food packaging, candy packaging (twisted film), drug packaging (infusion bag), on the album, folders and files and other fields instead of PVC, synthetic paper, adhesive tape, name card holder, ring folder and composite bag stand.

In addition, pasteurized milk is also available in roof type cartons and glass bottles.

Q: Which kind of transparent vacuum packing bag 16 wire and 24 wire?: The so-called silk is a unit, a trace of =0.01mm, from this point of view, the bag is thicker, the more difficult to leak, so the 24 wire than the 19 wire better.

Q: What are the common materials of tea packing bags?: PE bag (plastic bag)Polyethylene bags, or PE bags, are widely used packaging materials at present. There are two kinds of low density PE bags and high-density PE bags. The low density PE bags are breathable and breathable, while the high-density PE bags are smaller.The advantages of PE bag are economical, cheap and damp proof. Its disadvantages are light transmission and poor air resistance. It can not be used in tea packaging individually. The best can add a layer of light resistance and low permeability of the outside packaging using polyethylene bags, such as synthetic paper cans, cans and other PE bag permeability is bigger, also difficult to solve the problem of oxygen in the packaging bag, and is not the ideal packaging material.

Q: Printing solvent for food packing bag: Determine the amount of water in the solvent by means of the principle of a different dissolution effect. Take the most transparent glass cylinder tube with 100ml toluene solution, take a small amount of analyte ester solvent such as toluene, evenly pour. When you just pour in toluene, carefully observe whether there is turbidity (milk white) phenomenon. If there is this phenomenon, the water content of the solvent is seriously exceeded, and the experience shows that when the moisture content exceeds 0.5%, the phenomenon is obvious. The water content test of benzene solvent can be carried out by extracting solvent from the long glass tube to observe whether there is delamination.

Q: What material should be used for transparent packing bags? How many cents do you want?: Generally Po (polyolefin) material, you can also use PE (polyethylene) material, PP (polypropylene) material, to see your specific needs

Q: What can be easily removed from the words printed on plastic bags?: Dyes can be classified according to their purpose, state, or origin. Remove the upper part of the plastic bag from the fuel. Refer to
