Vacuum Forming: It is a transparent plastic with a specific convex shape made of a transparent plastic hard sheet by the Vacuum Forming process. It is covered on the surface of the product to protect and beautify the product. It is also called Vacuum Forming and vacuum cover.
What should be paid attention to in card insertion packaging?
Card insertion packaging refers to a packaging form in which a paper card is inserted into a transparent Vacuum Forming with three sides folded. Its characteristic is that no packaging equipment is required during packaging. Only workers need to put the product, Vacuum Forming and paper card in place.
The issues that should be paid attention to are:
1. The paper card and the Vacuum Forming with folded edges are of appropriate size. If they are inserted too tightly together, the paper card and Vacuum Forming will be deformed; if they are too loose, they will easily fall off.
2. When the product is too heavy, it is necessary to consider using staples to fix the paper card and Vacuum Forming at a certain position.
What should be paid attention to in Vacuum Forming card packaging?
Vacuum Forming packaging refers to the heat-sealing of a Vacuum Forming on the surface of a paper card with Vacuum Forming oil. This type of packaging is commonly used in supermarket batteries. Its characteristic is that it requires a Vacuum Forming sealing device to encapsulate the product between the paper card and the Vacuum Forming.
The issues that should be noted are:
1. The surface of the paper card must be coated with Vacuum Forming oil (so that it can be heat-sealed with the PVC Vacuum Forming);
2. The Vacuum Forming can only be made of PVC or PETG sheets;
3. Because the Vacuum Forming is only glued to the surface of the paper card, the encapsulated product is not easy to be too heavy.
What should be noted about double Vacuum Forming packaging?
Double Vacuum Forming packaging refers to a packaging form that uses two Vacuum Formings to encapsulate the paper card and the product together. Its characteristic is that it requires a high-frequency machine to seal the double Vacuum Forming edge, which is low in efficiency and high in packaging cost, but the edges are neat and beautiful, and the product appearance is high-end.
The issues that should be noted are:
1. Only PVC and PETG films can be used for the Vacuum Forming, otherwise it cannot be heat-sealed or the heat-sealing effect is poor;
2. The quality of the high-frequency mold determines the quality of the edge of the double Vacuum Forming.
What issues should be noted for half-Vacuum Forming packaging?
The full meaning of half-Vacuum Forming packaging is half-exposed double Vacuum Forming packaging of products. It refers to the packaging form in which the paper card and the product are packaged together with two Vacuum Formings, but the product is partially exposed outside the Vacuum Forming. It is suitable for particularly long products. Its characteristic is that it is necessary to manually cut the exposed part of the Vacuum Forming with scissors first, and then use a high-frequency machine to seal the double Vacuum Forming. The efficiency is low and the packaging cost is high, but the visual effect is good, and it can meet the needs of users to directly touch the product when picking goods in the supermarket.
Problems that should be noted:
1. Products that are easy to get dirty are not suitable for this type of packaging;
2. When cutting holes in the Vacuum Forming, pay attention to the neat edges;
3. The Vacuum Forming must be made of PVC or PETG hard sheets.
What should be noted about external semi-Vacuum Forming packaging?
The full meaning of external semi-Vacuum Forming packaging is that all products are placed outside the double Vacuum Forming, and the double Vacuum Forming only encapsulates the paper card and serves as the base of the product head. The product and the Vacuum Forming are connected with plastic straps. Its characteristics are that a high-frequency machine is required to seal the double Vacuum Forming and punch strap holes on it. It has the lowest efficiency and high packaging cost, but it can meet the user's need to touch the product.
What should be noted about folding Vacuum Forming packaging?
Folding Vacuum Forming packaging refers to the side of the double Vacuum Forming being connected together during the Vacuum Forming forming process, and the bottom and surface of the double Vacuum Forming are formed after being folded. Its characteristics are that it does not use high-frequency edge sealing technology, but makes buckles at certain positions of the Vacuum Forming to connect the double Vacuum Forming, and can also be stapled when necessary. In terms of material selection, PET hard sheets can be used to achieve the purpose of environmentally friendly materials.
Problems that should be paid attention to:
1. Because there is no high-frequency machine edge sealing, the edge needs to be cut on the cutting bed with high quality;
2. The tightness of the buckle position should be moderate.
What should be paid attention to in tri-fold Vacuum Forming packaging?
Tri-fold Vacuum Forming packaging is to fold the Vacuum Forming into three sides (front, bottom, and back), forming an extra bottom edge so that the product can stand on a flat surface. Its characteristic is that it does not use high-frequency edge sealing technology, but makes buckles at certain positions of the bubble shell to connect the bubble shell, and can also be stapled when necessary. In terms of material selection, PET hard sheets can be used to achieve the purpose of environmentally friendly materials, which is suitable for large-caliber product packaging.
Issues that should be noted:
1. Because there is no high-frequency machine edge sealing, the edge needs to be cut on the cutting table with high quality;
2. The tightness of the buckle position should be moderate.
