What are the functions and functions of packaging bags

The composite packaging mask bag is two or more materials, which are combined through one or more dry composite processes to form a composite packaging with certain functions.
Generally, it can be divided into base layer, functional layer and heat sealing layer. The base layer mainly plays the role of beauty, printing and moisture resistance.
Such as: BOPP, PET, etc.; the functional layer mainly plays the role of blocking and avoiding light, such as VMPET, AL, etc.;
Adaptability, permeability resistance, good heat sealability, as well as transparency, openness and other functions, such as LDPE, LLDPE, MLLDPE, CPP, VMCPP, etc.
Features of the mask aluminum foil bags and cosmetic packaging bags produced by our company:
(1) Strong air barrier performance, anti-oxidation, waterproof and moisture-proof.
(2) Strong mechanical properties, high blast resistance, strong puncture resistance and tear resistance.
(3) High temperature resistance (121℃), low temperature resistance (-50℃), good oil resistance and fragrance retention.
(4) Non-toxic and tasteless, in line with food packaging hygiene standards.
(5) Good heat sealing performance, good flexibility and high transparency.
Mask bag material:
It has high transparency, sterilization, anti-corrosion, moisturizing, fresh-keeping, good sealing, high tensile strength, strong hardness, longer storage time, and can also be customized according to customer requirements.
It is widely used in clothing, food, printing, stationery, cosmetics, paper and other industries. The middle layer AL has good resistance
Barrier, play a good light blocking effect. PE: has good corrosion resistance, electrical insulation, flexibility, elongation, impact strength and permeability.

Mask bag features:
The pattern is clear, the bag surface is smooth, anti-leakage, no foaming, and can print various patterns and logos. Our company has advanced testing equipment and perfect inspection equipment.
Testing system to ensure product quality, welcome business friends from all walks of life to call and write to discuss business.

The scope of application of the mask bag:
Eye patch bag, neck patch bag, facial mask bag, medical plaster bag, cold compress, hot compress and other packaging bags.

The vacuum packaging machine is a vacuum inflatable package to pack the food into the packaging bag. After the air in the packaging bag reaches a predetermined vacuum degree, nitrogen or other mixed gas is filled, and then the sealing process is completed.
Changshu Yaxuan has been committed to the research and development of vacuum packaging machines for a long time, absorbing foreign advanced technology, and has developed four series of vacuum packaging machines: food vacuum packaging machines, small vacuum packaging machines, desktop vacuum packaging machines, single-chamber vacuum packaging machines, The equipment of double-chamber vacuum packaging machine and three-dimensional bag vacuum packaging machine has reached the level of Europe and the United States. And provide quality, technology, vacuum packaging machine price guarantee 100% satisfaction, recognized by foundation bottle Suppliers the majority of customers. The series of vacuum packaging machines produced by the company are suitable for vacuuming, inflating and body-fitting packaging machines for various foods, meat products, seafood, fruits and vegetables, pickles, chilled meat, pharmaceutical products, hardware components, medical equipment, etc.
The principle of vacuum packaging is: because the mildew of food is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen to survive, and vacuum packaging uses this principle to put the food inside the bag and the food. The oxygen in the cells is pumped out, so that the microorganisms lose their "living environment". Experiments have shown that when the oxygen concentration in the packaging bag is less than or equal to 1%, the growth and reproduction rate of microorganisms will drop sharply. When the oxygen concentration is less than or equal to 0.5%, most microorganisms will be inhibited and stop multiplying. (Note: vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzymatic reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt pickled etc.)
