Q:What are the packaging forms of fresh milk?
Pasteurized milk as milk sterilization, the glass bottle packaging plastic bags or plastic bottles, plastic bags are simple, like using the monolayer polypropylene material, because these materials are difficult to achieve in aseptic filling and sterilization of milk filling environment, generally do not take aseptic production, such products require cold chain transportation, and shelf life short, usually within 3 days, but the fresh sense of strong, low packaging cost, cheap price. In addition, pasteurized milk is also available in roof type cartons and glass bottles.
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:What kind of material is the urea packing bag made of?
The main material of urea woven bags consists of polypropylene and polyethylene.
Q:What are the soft and hard sides of plastic bags? Material or process technology?
The quality of plastic packaging is determined by both the material and the process. The material is no better than the good one. But the hardness of plastic is not a decisive factor in determining the quality of plastic, mainly to see what the use of what needs to keep products
Q:Dried fish vacuum packaging packing bag can not puncture
With dried fish, we recommend the use of aluminum foil bag, also can be vacuumized. It has the function of avoiding light and keeping fresh.
Q:What's the raw material of the cement packing bag?
The quality of cement packing bags directly affects the shelf life of cement. Bags of cement raw material is polypropylene resin, mainly for foreign production of polyethylene (PE), mainly for the domestic production of polypropylene (PP), then add some additives, after the heating wire drawing, then weaving, printing and so on, the higher the quality of the cement bag inner lining!
Q:What are the characteristics of a good package?
This mainly refers to the packaging can perfectly protect and preserve the goods in the design of material selection, structure, can effectively cooperate with transportation storage loading and unloading circulation operation; enable consumers to use the goods, carrying and preservation is more convenient. In addition, whether the packaging material will cause pollution to the environment, and whether recycling is also very important. Packaging industry is a scientific and systematic project, and the packaging design must take into account the scientific aspects of each link, which also reflects the combination of art and science characteristics.
Q:Plastic packing bag printing color
A few silk thickness, a trace is 0.01mm, the more thick material, certainly the higher the price, so in ensuring the strength of your plastic bag, with thin point more money.
Q:The vacuum packing bag is sealed. How can I open the zipper?
You can pull the zipper tail, the zipper straightened, and then repeatedly from the bottom up, check whether smooth, if not smooth, often because the zipper stuck in other things, so it is not smooth, only need to remove obstacles, you will be back to normal.
Q:What material is the vacuum packing bag?
Vacuum packaging is a general term for flexible packaging composite membrane products. If the temperature is different, there will be a lot of division: there is less than 100 bactericidal, and some need 100 degrees of sterilization, and 121 degrees and 135 degrees.
