Q:What ink is the food packing bag printed on?

At present, in the food plastic packaging and printing, the most widely used is the benzene soluble chlorinated polypropylene ink series. This series of ink production and application technology have been very mature, is mainly used for the gravure printing in BOPP (BOPP) on printing and printing adaptability is very excellent, good processing performance, faster drying. However, there are still many deficiencies in this method of printing.

Q:How many kinds of packing bags are there in the packaged foods?

PE's softness and mechanical properties are worse than those of PP. It represents shopping bags, plastic wrap, garbage bags and so on.PP is stiffer, anisotropic (with a notch that is easily ripped), has good mechanical properties, and is superior to PE in high-temperature performance, representing bread bags.I wonder if this answer has met your requirement.

Q:Printing solvent for food packing bag

Use a moisture indicator to determine the content in the solvent. The water indicator is put into the solvent, and the water content varies with different colors. Depending on the color change, the amount of water in the solvent can be roughly determined.

Q:What products need plastic packing bags?

Plastic packaging is almost everywhere.

Q:Three layer coextrusion material for packaging bags

Five layer co extruded films composed of outer layer of multi ester copolymer, high mechanical strength, the second layer is ethylene methacrylate polymer, the third layer is the fourth layer of polyethylene, polyethylene, the inner layer is modified with ethylene propylene polymer. Five layer co extruded films performance of each layer as outer layer: providing excellent heat sealing and protection, good printing performance; the second layer is connected with the outer layer and third layer; third layer: providing vapor barrier and softness; fourth layer: connection layer and the third layer; inner layer: non-toxic, with compatibility infusion product good, excellent heat sealing and buffering external impact.

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 does "13 silk" in vacuum packing bag mean?

The wire unit is 1/1000 points, the general use vernier caliper, micrometer, gauge with smaller, can be measured. According to the determination, a hair diameter of about five to seven silk (ie 0.05 ~ 0.07), "a trace" is a very small unit. The wire is called the habit of CMM, and other transformation between the length of the unit is:1 mm = 100 wire (tract)1 =10 =0.1 decimillimeter centimillimeter micrometer wire =1 =0.01 mm =0.001 cm =0.00001 meters

Q:Can food wrap be heated in a microwave oven?

A package or container that is not suitable for microwave heating:1 metallic or metallic or metallic (absolutely not)2, if the porcelain with metal decorative patterns, it can not.3 、 special plastic for non microwave oven and special plastic film for non microwave oven.4, all containers that do not indicate microwave heating are not recommended.

Q:Why a lot of the packaging bag surface is silver foil?

Because candies are also considering moisture side so many sweets are wrapped in wax paper (because the wax paper can prevent water entering)For example, chocolate is a special kind of candy, its melting point is 36 degrees, it is very easy to get the temperature melting in the hand, so the reason is tin tin foil, the hands of the temperature can be very good to pass out to prevent the chocolate melts quickly.

Q:What kind of packaging bag does polysilicon use?

Packing should be prevented from damage to polyethylene packing bags to avoid external contamination and provide good protection. It should be high pressure.
