Q:Printing solvent for food packing bag

Smell the smell of solvents. Contact with commonly used solvents, smell, after a long time, the odor of a particular solvent has a rough impression. If the odor of the batch solvent is not pure, it is certain that the purity of the batch solvent is not high or the impurities are more. In addition, the solvent is applied to a clean plastic film to compare its basic odor before and after volatilization, and the tendency of residual solvents can be roughly judged.

Q:Should the food packaging bags be labeled with QS markers?

QS labels should be affixed, but the manufacturer's own QS is not affixed to the manufacturer of the packaging, but the packaging supplier must print its QS number on the outer package of the package to the manufacturer.

Q:Dried fish vacuum packaging packing bag can not puncture

If the choice of transparent vacuum packaging bag can also, without aluminum foil bags, good quality effect.

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:Printing process of packaging bag

When printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the image part, so as to form the same picture and text as the original. The screen printing equipment is simple and easy to operate. The printing and plate making process is simple, low cost and adaptable. Printing screen printing application scope is broad common: color paintings, posters, name card is designed to cover commodity signs and textile printing and dyeing etc.

Q:What about the table of nutrition values on food packages?

Since each manufacturer may have different sizes of "one", it is better to use 100 grams or 100 milliliter units when comparing the nutrients in a similar product. Quantity of heatHeat is often listed in thousands of joules, and, where possible, the least calorie products should be selected. ProteinIs the total protein content in the food, G is the unit of measurement.

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 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?

First, it is easy to heat seal, otherwise only aluminum foil can not be sealed;Two, high barrier plastic film preservation effect is also very good, can increase its number of layers, reduce aluminum foil thickness, thereby reducing costs

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