Q: What products need plastic packing bags?
Need to use plastic bags do not have too much garbage bags, food bags, beverage bags, commodity bags, clothing bags, plastic bags are closely related to human, as long as you want, we can use plastic bags for packaging, plastic just different ingredients. Because plastic bags are convenient to carry and relatively low cost, they are well known to people.
Q: The package specifications are 9 multiplied by 14 plus 3. How big is it?
Now the standard of living has improved, basically vacuum packed bags. This will improve the product's shelf life, preservation time is longer, more conducive to product sales.
Q: How to evaluate the quality of a food packaging bag design? From what angle?
Successful packaging must be eye-catching. This can only be used as a horizontal contrast. In the same environment, the most striking one is the one that can be distinguished from other products at one glance. Also take the moon cake as an example, the Mid Autumn Festival, the general moon cake gift box is red, golden yellow based, above is not the moon, is the flower, most of them are like this. If the design is blue, the package is also shown in the same area. Must be the most striking.
Q: What is the material of detergent bag?
Polypropylene English Name: Polypropylene, abbreviation: PP, commonly known as: 100 fold glue. Polypropylene is a representative of poly - alpha olefins, a thermoplastic resin made by the polymerization of propylene. Its monomer is propylene CH2=CH - CH3. According to the initiator and polymerization process, polypropylene can be divided into isotactic polypropylene and random polypropylene and syndiotactic polypropylene three configurations. Isotactic polypropylene is easy to form crystalline, high crystallinity reached more than 95%, the molecular weight of 8-15 million, giving it a good thermal and solvent resistance; atactic polypropylene at room temperature is white wax microstrip viscous a non crystalline, low molecular weight, in 3000-10000, the lack of irregular structure cohesion, application.
Q: What are the requirements of the mark on the cement packing bag?
The cement packing bags shall clearly indicate the standards of implementation, cement varieties, codes, strength levels, producers' names, production licence marks (QS) and serial numbers, serial numbers, date of packing and net contents. Bags on both sides should be based on the varieties of cement with different color printing name and cement strength grade, Portland cement and ordinary portland cement Portland slag cement by using red, blue gray volcano; Portland cement and Portland fly-ash composite silicate cement by sleep and black or blue..

Q: The shelf life of the package usually takes several forms
Food soft packing materials mainly include polyethylene, polypropylene, polyester, polyamide and other polymer materials. These packing materials show great differences because of their molecular structure, forming process and additives. Therefore, for food manufacturers, choose a suitable packaging for their products is particularly important, otherwise there will be food safety issues.
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?
Aluminum filmThe first consideration of food packaging is the barrier properties of packaging materialsBecause barrier property is good, the preservation time is long, the shelf life is long, the quality can guarantee betterAt present, all food packaging materials, aluminum foil barrier is the best (followed by some high polymer plastics, like EVOH, PVDC, etc.)Therefore, the most common, always in the middle of two layers of plastic film, a layer of aluminum foil, to improve barrier,But why not use aluminum foil packaging alone, but also two or more layers of plastic film?,
Q: What ink is the food packing bag printed on?
1, ink contains toluene, printed products residual solvent value is higher;2, chlorinated polypropylene heat stability is poor, easy to release chlorine, and in the air to form hydrogen chloride (commonly known as hydrochloric acid), making the ink showing a strong acid, the printing roll corrosion;3, benzene soluble ink can also release ozone depleting substances, in the process of production and use, it may produce damage to the production worker body, at the same time in the finished product is easy to residues of harmful substances, so the food packaging bag to cause pollution;
