Vacuum Skin Packaging Mmachine
Vacuum skin packaging is a new packaging technology in Europe and America. After packaging, the product is tightly attached between the film and the substrate.In production, the trouble of manual bagging is eliminated. After packaging, the three-dimensional feeling is strong, and customers like to buy. Frozen foods can be packaged directly in a frozen state. The transparent film is softly attached to the product and the tray so that the soft article does not break the shape after packaging.Can better maintain the original look.
What is skin packaging?
The skin packaging method is to heat and soften the packaging film, and at the same time, evacuate the film under the bottom plate and paste the film onto the product according to the shape of the product. The bottom plate can be: a color printing paper card, corrugated cardboard or cloth.
Skin packaging machine application range
Skin packaging applications are mainly divided into three categories:
First, commercial visual display packaging: hardware products, color card printing, play the role of store shelves visual display packaging.
Second, industrial shockproof packaging: the use of transparent foam base film or corrugated cardboard, cushioning shockproof products.
Third, food vacuum preservation: such as fresh meat, fish, aquatic products (shrimp, oysters, etc.), poultry, pet food, etc., visual display effect is good, fresh, product shelf life is long, easy to use, sales are also convenient.
Advantages of skin packaging
1. Regardless of size, shape, alone or in combination, the product can be sealed at one time without any mold, convenient, flexible, practical and efficient.
2, the stereo effect is strong, the product is clearly visible, and the product value and grade are effectively improved.
3, the product is completely fixed between the cardboard and the film, with dust, shock and moisture resistance.
4. Compared with traditional protective packaging, it can reduce packaging volume and reduce storage and transportation costs.
5. High-grade ultra-transparent visual display packaging, greatly enhancing the competitiveness of the product market.
6. The skin vacuum packaging machine can save bagging time, and since the transparent film is closely attached to the article, water vapor is not generated on the package as compared with the package covered only on the disk, and drying can be prevented.
7. Since the upper transparent film and the lower transparent film (shallow plate, cardboard) are directly bonded together, water droplets are less likely to flow out and water in the article can be prevented from appearing.
8. Frozen foods can be packaged directly in a frozen state. The transparent film is softly attached to the product and the tray so that the soft item does not break the shape after packaging.

Body-fitted packaging film
PE skin packaging film (PE body-fitted film) is a kind of PE film. PE film has good toughness, moisture resistance and heat sealing properties, good processing and forming properties, and low price.
1. Low density polyethylene film. Extrusion blow-moulded T-LDPE film is a kind of non-toxic and odorless flexible transparent film. After adding viscous, it is very suitable for PE body-fitted packaging film. The thickness of LDPE films is generally between 0.02 and 0.1g. Low density polyethylene (LDPE) film has the advantages of high permeability, no aroma and poor oil resistance. It can not be used in the packaging of oxidized food, flavor food and oily food. But breathability allows it to be used in fresh fruits, vegetables and other fresh packaging.
2. High density polyethylene film. HDPE film is milky white, indicating poor gloss, a tough translucent film. The tensile strength, heat resistance, oil resistance, moisture resistance and chemical stability of HDPE film are better than those of LDPE film, and it can be heat sealed, but its transparency is not as good as that of LDPE. Packaged food has poor air tightness, no fragrance and short storage period. HDPE film has good heat resistance and can be used as heat sealing layer for cooking bags. High density polyethylene film is not suitable for PE body-fitted packaging film.
3. Linear low density polyethylene film. LLDPE film is a new product of polyethylene film. Compared with polyethylene film, LLDPE film has higher tensile strength, impact strength, tear strength and durability. The thickness of LLDPE film can be reduced to 20-25% of LDPE film with the same strength and properties as LDPE film, which greatly reduces the cost. Even if used as heavy packaging bags, its thickness can meet the requirements, only 0.1 can replace the price of high polymer, high density polyethylene. Therefore, LLDPE is suitable for daily necessities packaging, frozen food packaging, as well as a large number of heavy-duty packaging bags. Linear low density polyethylene film, mainly used for packaging circuit board, that is, circuit non-vacuum body-fitted packaging film (circuit board vacuum packaging film)
