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:Dried fish vacuum packaging packing bag can not puncture

Anti piercing vacuum packaging bags, first of all, choose the material of the bag to have toughness, followed by the thickness of the bag

Q:How can the labels affixed to the bags be removed quickly?

Use the lighter directly on the other side of the metal label to burn for a while. The glue on the label will melt quickly. This method works fastest and works best, but it only works for metals.

Q:What are the requirements of the mark on the cement packing bag?

Cement gradeCement is divided into strength grade: 1, Portland cement strength grade is divided into 42.5, 42.5R, 52.5, 52.5R, 62.5, 62.5R six levels. 2, ordinary portland cement strength grade is divided into 42.5, 42.5R, 52.5, 52.5R four grades.3. The strength grades of slag Portland cement, volcanic ash Portland cement, fly ash Portland cement and composite Portland cement are divided into 32.5 grades: six, 32.5R, 42.5, 42.5R, 52.5 and 52.5R.

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: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 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 material is the packing bag for pure milk, please?

Packaging engineering, 2008, 29 (12): 56-58.lixixiao2 (in TA) food grade polyethylene chen.1fan (TA station) composite layer of aluminium metal and linear PE, the middle layer there should be consistent with FDA zznjut (station link TA) composite and 100% more than one layer of polymer should be PE, the rest of the aluminum foil paper, duanyanjian (station TA) aluminum composite paper plastic bag

Q:What are the advantages and disadvantages of OPP and CPP membranes? What kind of bags are they used for?

CPP films have the characteristics of good transparency, high gloss, good stiffness, good moisture resistance, good heat resistance, and easy to heat sealing. CPP film is printed and bag made

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.
