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:Three layer coextrusion material for packaging bags

At present, there are mainly two kinds of non PVC multilayer coextrusion infusion membrane: three layer structure and five layer structure.The performance of the layers of the three co extruded films for outer: block air, good printing performance; the middle layer with water resistance and anti permeability and elasticity; inner: non-toxic, good heat sealing and elasticity, and the solution has good compatibility.

Q:Antistatic packaging bag with chip

Black bag production with carbon black, which has a conductive performance, can be generated by friction when the chip electrostatic conductive bag release, however, strictly speaking, conductive black bag, only release the function of static, anti-static must be placed in the box or the box, in order to play the effect.

Q:How do I remove the self-adhesive label affixed to the plastic bag?

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:How much is the 1 wire in the food packing bag printing industry?

1 wire =0.01 mm, refers to the thickness of the bag units!Custom food packaging bags, I recommend to have experience in custom food packaging bag manufacturers, because it can reduce the cost and time for many of you, can give you a lot of packaging design and customized recommendations.

Q:Why are some teas not vacuum packed?

Feng Xing packaging machinery factory experts explained that the main role of vacuum packaging machine is oxygen, moisture, high temperature fermentation, etc., in order to prevent the deterioration of tea. The principle is relatively simple, which is conducive to vacuum packaging machine to remove the air in the packaging bag, and then sealed, so that tea in a vacuum under the state, and absolutely isolated from the outside world.

Q:Is the packet in the food package a reducing agent or an oxidizing agent?

Take active ferric antioxidants as an example;Due to the activity of iron is extremely fine powder, high surface area, the rate of reaction with oxygen is faster. Reduced iron powder. In general, the reaction equation is 4Fe+3O2+6H2O=4Fe (OH) 3, and iron corrosion reactions may also occur.Followed by iron powder particles will adsorption of these smaller food packaging bags in water, the water, in part from within the food, in part from nature. After absorbing most of the excess water, the relative humidity in the food package can be kept constant, which plays a very important role in controlling microbial pollution.

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

It depends on the label on the package. If it can be marked with microwave heating, you can not.

Q:Can aluminum packaging bags be recycled?

Pure aluminum foil packaging: such as barbecue foil, baked aluminum foil, fast food aluminum box (air fast food), because users scattered, recycling is difficult, there is no recycling reports.

Q:The package specifications are 9 multiplied by 14 plus 3. How big is it?

Custom vacuum packing bag, I recommend to have experience in custom vacuum packaging bag manufacturers, because it can reduce the cost and time for many of you, can give you a lot of packaging design and customized recommendations.
