The packaging method of the shrinking machine

the packaging method of the shrinking machine

during the shrinking process, the shrinking machine does not affect the quality of the packaging, but can shrink quickly and perfectly. The packaged products can be sealed, moisture-proof, impact resistant, and suitable for tight packaging and pallet packaging of multiple items

packaging method of shrinking machine 1. Open type at both ends

it uses cylindrical film or flat film to wrap the package in a sleeve first, and then carry out heat shrinkage operation. After packaging, there is a shrinkage opening at both ends of the package

(1) when using the cylindrical membrane, first open the opening of the cylindrical membrane, then push the product into the cylindrical membrane with the help of the chute, and then cut off the membrane. As shown in Figure 1. This method is more suitable for wrapping cylindrical objects, such as batteries, paper rolls, bottles and cans. The advantage of using cylindrical film packaging is that it reduces 1 ~ 2 sealing seams and puts the ceramic aluminum industry in an important position in the development of Huaibei industry. The process has a beautiful appearance, but the disadvantage is that it can't adapt to 1. The reducer under the workbench should meet the requirements of product diversification and is only suitable for mass production of a single product

(2) wrap articles with flat film in two ways: single flat film and double flat film. The film should be wider than the article. Wrap it with two flat films, that is, wrap it with the upper and lower films. When the previous package completes the sealing and cutting, the two films are sealed together, and then push the product to the vertical film by machine or manually. After it is in place, the sealing and cutting mechanism falls down, and seal and cut the other side of the product. After the product wrapped in the film is heat shrinkable, both ends of the package shrink to form an oval opening. When using a single flat film, First unfold the flat film, and feed the wrapped product towards the middle of the flat film to form a horseshoe shaped wrapping, and then reheat the lap seal

packaging method of shrinking machine 2. Four side sealing

wrap the product around with flat film or cylindrical film, and the joints are sealed by lap joint. Used for product packaging requiring sealing

(1) the L-shaped sealing method can be used to fold the film in half. The roll can be used to fold the film in half, pull the film out for a certain length and place it in a horizontal position, prop up the open end mechanically or manually, and push the product to the crease

(2) pillow bag packaging can be used with a single flat film. This method is to use a single upper and lower jaw to tighten the flat film, first seal the longitudinal seam into a cylindrical shape, push the product into it, and then seal the transverse seam to cut it into a pillow shaped package or punch and bind both ends into a cylindrical package

(3) the double flat film four side sealed packaging is similar to the two end open packaging, which can be completed only by equipping the machine with sealing devices on both sides

(4) if wrapped with cylindrical membrane, it is only necessary to seal, puncture and then heat shrink while the cylindrical membrane is cut off. There are often pricks next to the sealer. During heat sealing, the pricks prick vent holes on the film, and the small holes often close themselves after heat


shrinking machine 3. One end open

pallet shrinking packaging is a typical example. First, the film is made into a large bag with square bottom, and then the large bag is sleeved on the stacked commodity tray from top to bottom, and then heat shrinkable. Put the tray loaded with products on the conveyor belt and put on the shrink film bag; It is sent to the heat shrinkable channel by the conveyor belt, and the shrinkable packaging is completed after passing through the heat shrinkable channel. Its main feature is that the products can be firmly packed in a certain number of units, will not be loose during transportation, and can be stacked in the open air
