- Q: What kind of material is the packing bag of ceramic tile?
- The general is the use of a three paper membrane material, can play a waterproof effect, and not easy to damage, for this paper packaging, you can also consult some packaging manufacturers to see, for example, Hengyi Lihong, sincerity of these packaging manufacturers.
- Q: What is the material of detergent bag?
- Polyethylene (polyethylene, referred to as PE) is a thermoplastic resin made by polymerization of ethylene. Industrially, it also includes copolymers of ethylene with a small amount of alpha olefins. Polyethylene is odorless, non-toxic, feel like wax, has excellent resistance to low temperature performance (minimum temperature up to -100~-70 degrees C), good chemical stability, erosion resistance to most acid-base (not resistant to oxidizing acid). At room temperature, insoluble in general solvents, low water absorption, good electrical insulation.
- 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 are the advantages and disadvantages of OPP and CPP membranes? What kind of bags are they used for?
- (steaming film) CPP, good heat resistance. Because the softening point of PP is about 140 DEG C, this kind of film can be used in hot filling, retort bags, aseptic packaging and other fields. With acid, alkali, grease resistance, making it bread products, packaging or laminated materials and other fields of choice. Its contact with food safety, demonstration of good performance, will not affect the flavor of the built-in food, and can choose different grades of resin to obtain the desired characteristics.
- Q: The difference between a vacuum and a vacuum in a food package
- Vacuum and vacuum is actually a concept, the operation is generally called vacuum, are placed in the vacuum food packaging machine to extract air package a food packaging technology, will conduct disinfection operation in food bagging before or after bagging, its essence is no different.
- Q: Printing process of packaging bag
- If it is cut into pieces, use a special press for packing bags or screen printing.Screen printing, screen opened relatively simple, but the requirements of the substrate surface is relatively smooth, simple process, relatively low cost, but the adhesion of the ink requirements are relatively high.
- Q: What is the difference between LDPE and PE-LD in a package?
- LDPE is a low density polyethylene, environmental protection bag production is one of the raw materials, commonly known as low material, another raw material of HDPE is also called high pressure materials, packaging film, the two materials are mixed according to a certain proportion and then blowing, printing, cutting, packing bag made of,PE-LD is a common environmental protection mark printed on top of the packing bag, which indicates that the manufacturer is using an environmentally-friendly plastic bag.
- Q: Why is the higher the elevation, the more food bags inflate? From a physical point of view
- Because the food packaging bag is sealed, the air pressure inside is certain, with the elevation of the outside air pressure gradually decreased, which leads to gas bag outward extrusion pressure increased, so the higher the altitude, the food packaging bag inflated more.
- 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: How about the material difference of food packaging bag?
- Reason: PE has better heat sealing property, which is easy to sealPA has better printability and is used in the outer layer to print beautiful picturesPVDC EVOH, good separation performance, prevent oxidation. The film closed light is good, not easy to see the light of the product is appropriate.Specific more professional, no longer introduce one by one
