Q:What is the material for edible fungus stick packing bag?

High pressure polypropylene bag, the bag has the characteristics of high temperature and high pressure, it can reach 120 degrees and not easily deformed. It is the first choice for factory cultivation.

Q:Do vacuum packing bags have to be vacuum packed?

Vacuum packaging bags and vacuum packaging machines are related. Vacuum packaging machine not only can complete vacuum extraction, but also can complete heat sealing packaging in vacuum, and ensure vacuum in vacuum bag can meet the requirement.

Q:What is the difference between LDPE and PE-LD in a package?

LDPE is low density polyethylene, and PE-LD should be low density polyethylene. Because according to the PE classification, LDPE (low density polyethylene), MDPE (medium density polyethylene), HDPE (high density polyethylene), VLDPE (low density polyethylene), LLDPE (linear low density polyethylene (mPE), metallocene PE). See, "LD" means "low density".

Q:What material is the vacuum packing bag, please?

Of course, there is also room temperature, the choice of this temperature under the condition of the sterilization method is irradiation sterilization.

Q:What are the packaging forms of fresh milk?

In recent years, aseptic composite plastic bags and aseptic plastic cups have developed rapidly. Among them, the composite plastic bag adopts multi layer composite process, and aseptic cup packing adopts a plurality of multi-layer plastic coextrusion sheets to realize the molding, sterilization, filling and sealing of the container. These forms of packaging ensure the quality of fresh milk while enriching the packaging of fresh milk.There is also a plastic bottle of the two sterilized milk, general shelf life in March or more.

Q:The shelf life of the package usually takes several forms

Milk is extremely nutritious and therefore very perishable. In order to keep fresh and safe to consumers during circulation, the milk must be thoroughly sterilized and securely packaged. The sterilization method, compared with traditional pasteurization, the ultra high temperature sterilization (Ultra High, Temperature, UHT), can greatly reduce the milk color, flavor and nutritional value of the loss, and become the best and fastest way to the development of processing.

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?

Aluminum filmThe first consideration of food packaging is the barrier properties of packaging materialsBecause barrier property is good, the preservation time is long, the shelf life is long, the quality can guarantee betterAt present, all food packaging materials, aluminum foil barrier is the best (followed by some high polymer plastics, like EVOH, PVDC, etc.)Therefore, the most common, always in the middle of two layers of plastic film, a layer of aluminum foil, to improve barrier,But why not use aluminum foil packaging alone, but also two or more layers of plastic film?,

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?

Polysilicon shall be packed in a clean polyethylene packing bag and sealed;
