High Quality Cold-water-soluble Film Pod Machine From POLYVA

Beverage production is closely related to people’s lives. The high degree of automation of beverage filling, packaging and packaging processes is the source of power to increase production capacity. Therefore, beverage packaging and other industries are also facing new challenges. How to start with improving equipment performance and improve For the stability of the beverage packaging process, photoelectric sensors are widely used in all aspects of production packaging to complete various complex tasks to ensure that the transparent film enters the shrinking device uninterruptedly. The sensor must ensure reliability and stable detection when detecting transparent materials. The target object ensures reliable monitoring when the transparent stretched film enters the shrinking device and reduces the risk of incorrect packaging.

How to use PE protective film correctly? Source: Protective film factory direct sales Release time: 2020-01-03 Click: 13231 PE protective film is as easy to use as a tape. However, as the width and length of the protective film strip increase, the difficulty factor will also increase a little bit. The difficulty of handling a tape that is 4 feet wide by 8 feet long is different from the difficulty of handling a tape that is 1 inch wide by 4 inches long. A bigger challenge is to make a large piece of PE protective film perfectly aligned with the target surface, and then put it down without producing unsightly wrinkles or bubbles on the surface, especially on the surface of irregular products that are difficult to handle. In order to better stick the protective film on the surface of the product and make it as perfect as possible, we need at least two people. One person holds the protective film roll, while the other person pulls the torn end to the other end of the product that needs to be protected, sticks the end to the target surface, and then manually presses the protective film in place, facing the person holding the roll people. This method is very labor intensive and low in work efficiency, but the work effect is quite good. Another way to manually apply large pieces of PE protective film to large pieces of material is to apply the material to the film. The following describes a relatively simple method of applying a large (4.5 x 8.5 ft) surface armor to a 4 x 8 ft material. You will need a roll of double-sided tape and a utility knife. (Note: The problematic material should be able to tolerate a certain amount of processing before this method can run successfully.) How to perfectly stick the protective film on the surface of the product: 1. Prepare a suitable large and flat working space-more protection The objects are bigger-clean and free of dust, liquids or contaminants. 2. With the adhesive side facing up, unfold a small section of the protective film. Make sure it is smooth and wrinkle-free, and evenly attach the loose end to one of the double-sided tapes. 3. Continue to unfold the protective film and place it along the length of the working surface not far from the other double-sided tape. 4. Roll up the film and place it on top of the double-sided tape. Be careful not to pull the original connection end out of the tape. Adjust the direction of the film to ensure that the film is straight and free of wrinkles. It is properly tightened, but not so tight that the film will shrink later. (When the film is stretched during use, when the film tries to return to its original shape, the edges tend to pull up.) 5. Lower the film onto the second double-sided tape. Using a utility knife, cut the roll from the film that is now waiting to receive the sheet to be protected. 6. Place one edge of a piece of material on one end or one side of the protective film. Place it where the film is held by the double-sided tape. Gradually place the parts on the adhesive film. Note: If the material is flexible, when you place it on the film, bend it slightly to roll it up and allow air to escape between the material and the film. 7. To ensure that the sheet is attached to the film, apply pressure to the material, especially along all edges, to ensure good adhesion. A clean paint roller may be used for this purpose. 8. Use a utility knife to trace part of the outline on the protective film, cut off the excess film, delete the excess and dispose of it. Flip the part carefully, and if necessary, apply pressure directly to the film, working from the middle to the outside to ensure that the entire area adheres well, and check that the finished piece is intact and has no wrinkle coverage.

Analysis of common quality problems of PET film! Source: Protective film factory direct sales Release time: 2019-03-02 Click: 2805 The color of the PET film is yellow or gray or has yellow strips, especially when it is rolled into a reel, the color is yellow or gray. Use It can be seen by the naked eye. If there are yellow bars, you must unfold the film or observe the light. Or spread it on a white backing for better identification. Analysis of the cause The reason is the same as the gel point, yellow point and black point. Yellowing is caused by poor thermal oxygen stability of the resin or more air entering the extruder. When the resin is thermally oxidized, it produces a large amount of acetaldehyde. Because acetaldehyde reduces the antimony trioxide to antimony, the film (resin) turns gray. The appearance of yellow bars usually occurs after replacing the filter or after replacing the resin. The reason is that there may be air in the person during the replacement. , Or part of the resin stays in the machine for too long. It makes part of the resin yellow, and after the formation of these yellow resins, it is impossible to fully mix with the normal melting and plasticization, so yellow bars appear. 2. Static electricity One characteristic of excessive static electricity is adsorption. Rubbing the surface of the PET film, or peeling off the film roll, or when the film is running at high speed, will generate static electricity. If there is dust, paper dust, hair, etc. near the film at this time. It may be adsorbed and affect the quality of the product film (especially the capacitor film). When the static electricity is serious, it may also cause fires, electrical accidents and other accidents. It is known that the static electricity of the polyester film is too large, which will affect the subsequent processing and processed products. Undesirable effects, for example, the electrostatic size of the bonded PET film can be determined by an electrostatic tester at about 500v. The measurement shows that the electrostatic size of the two sides of the film is also different. The reason is that the PET film is a polar electrical insulating material, which makes it through friction The charge generated by the action of, shearing, etc. cannot be transferred away, and accumulates on its surface to form static electricity. The size of the static electricity of the PET film is related to the electrical properties of the resin body, the application of additives, and the film making process. Because they directly affect the surface of the film/ The structure and properties of the surface, such as the crystallinity of the surface layer, the number of polar groups and their orientation, the size of the contact area of u200bu200bthe two films, and other factors that affect the formation of static electricity. Based on this, it can also explain why the static electricity on both sides of the film is different. Solution a. Find out the reasons from the resin, additives, and process and solve them in a targeted manner; b. Use static eliminator C in film making and post-processing of the film, coat a conductive layer on the surface d, use antistatic agent/resin 3. The bonding strength of printing, compounding and aluminizing is not enough. For the box bonding strength of printing, compounding and vacuum aluminizing, self-adhesive tape is usually used as the inspection side. There are 3 types of quiet conditions: full peeling, partial peeling and non-peeling. Both of the two types are of insufficient drilling strength. The reason analysis is that the strength of the combination of PET film, ink and mink mixture is restricted by the surface tension of the PET film. The surface tension of the untreated PET film is 42~48N/S, which cannot be reached. The adhesive strength of the ink adhesive is required, so it is important to take some measures such as corona treatment to increase the surface tension to reach 55N/cm or more.
