1. Vacuum forming knowledge and common sense
Blister: a plastic processing technology that mainly involves heating and softening flat plastic hard sheets, using vacuum adsorption to attach them to the surface of molds, cooling and forming them. It is widely used in industries such as plastic packaging, lighting, advertising, and decoration.
Blister packaging: a general term for the production of plastic products using vacuum forming technology and the packaging of the products with corresponding equipment. Blister packaging products mainly include: blister, tray, blister box, synonymous with: vacuum hood, blister, etc. The vacuum packaging equipment mainly includes: vacuum forming machine, punching machine, sealing machine, high-frequency machine, and folding machine. The packaging products formed by packaging can be divided into: card insertion, card suction, double bubble shell, half bubble shell, folded bubble shell, triple folded bubble shell, etc.
Bubble shell: Using vacuum forming technology to make transparent plastic hard sheets into specific protruding shapes of transparent plastic, covering the surface of the product to protect and beautify the product. Also known as bubble hood or vacuum hood.
Tray: also known as plastic inner tray, made of plastic with specific grooves using vacuum forming technology to protect and beautify products by placing them in the grooves.
Plush tray: It is a type of vacuum formed tray made of special materials, in which a layer of velvet material is attached to the surface of ordinary plastic hard sheets to give the tray a velvet like feel, which is used to improve the grade of packaging products.
Anti static tray: It is a vacuum formed tray made of special materials, with a surface resistance value of less than 10 ^ 11 ohms. Mainly used for vacuum formed trays of electronic and IT products.
What is double bubble shell packaging?
Double bubble shell packaging refers to a packaging form in which two bubble shells are used to package paper cards and products together. Its characteristic is that it requires a high-frequency machine to seal the edges of the double bubble shell, which is inefficient and has high packaging costs. However, the edges are neat and beautiful, and the product appearance is high-end. The issue to be noted is that: 1. Only PVC and PETG film can be used for the bubble shell, otherwise it cannot be heat sealed or the heat sealing effect is poor; The quality of the edge of the double bubble shell is determined by the quality of the high-frequency mold.
2. What is suction card packaging?
Card suction packaging refers to the heat sealing of blister packs onto the surface of paper cards with vacuum formed oil, which is commonly used in supermarket battery packaging. Its characteristic is that it requires vacuum sealing equipment to encapsulate the product between the paper card and the blister. The issues to be noted are: 1. It is required that the surface of the paper card must be coated with vacuum forming oil (in order to be able to heat bond with the PVC foam shell); 2. The foam shell can only be made of PVC or PETG sheets; 3. Because the blister only sticks to the surface of the paper card, the packaged product is not easily too heavy.
What is card insertion packaging?
Card insertion packaging refers to the packaging form in which paper cards are inserted together with transparent bubble shells folded over three sides. Its characteristic is that no packaging equipment is required during packaging, only workers need to place the product, bubble shells, and paper cards in place. The issues to be noted are: 1. The size of the paper card and the folded bubble shell is appropriate, and if they are inserted too tightly together, the paper card and bubble shell will deform; Being too loose can easily lead to detachment. When the product is too heavy, it is necessary to consider using staples to fix the paper card and blister at a certain position.
4. What is flocking and vacuum forming?
It is a type of vacuum formed tray made of special materials, in which a layer of velvet material is attached to the surface of ordinary plastic hard sheets, giving the tray a velvet like feel and improving the quality of packaging products.
5. What is a vacuum formed box?
In a broad sense, it refers to all blister shells, and in a narrow sense, it is just a type of blister shell: formed into a plastic box shape by sheet metal vacuum forming, with the lid connected to the container. It is often made of PS, and there are also those that separate the lid and bottom. Different materials can be used. For example, Japanese fast food boxes use black PS for the bottom and transparent PET for the lid.
