As we all know, the inner diameter sizes of easy-tear cans and cans are 52/65/73/83/99/126/152mm, but the sizes of potato chip cans most commonly used in the market are only 65 and 73, which stops many customers who want to innovate here. From December 2023 to now, many customers hope that we can make the size of potato chip cans according to the size of our easy-tear cans. OK! Arrange! Now our potato chip cans have successfully developed 52/83/99/126mm. Welcome to inquire.
The easy-tear cans and potato chip cans we use are two different can types, so the two cannot use the same mold. The working principle of the easy-tear cans we use is to expand the edge of the paper can outward, while the working principle of the potato chip cans is to roll the edge of the paper can outward 360 degrees.
There are two types of bends on the market, one is 180 degrees and the other is 360 degrees. The opening edge at the top of the paper can is the cross section of the cut tube. Although the inside and outside of the can are waterproof, if the cross section is not well protected, it is easy to be penetrated by water. Paper has a very strong water absorption. Once the cross section is soaked, water molecules will penetrate all the way along the paper can, causing the food inside to deteriorate. Therefore, we chose to improve our workmanship principle so that the bend can have 360 degrees, so that the aluminum foil inside can perfectly prevent the infiltration of external water molecules and form a strict waterproof barrier. However, the cross section of the 180-degree bend is still exposed to the outside, which makes it easy for water molecules to penetrate into the can in a humid environment.
The first is the traditional sealing process. You need a machine to heat the aluminum foil, so that the aluminum foil is heated and melted into the aluminum foil lining. After cooling, they can be firmly bonded together without glue.
The second type is aluminum foil with its own glue. Because the cost of an aluminum foil can sealing machine is about $2,400, some startups really can't afford to spend so much money on trial and error. Therefore, we have launched a self-adhesive aluminum foil, which you can tear off and stick on the top of the paper can. The glue we use is acrylic glue, which is colorless, odorless and has high adhesion. Although the sealing is not as good as the machine sealing, it can also meet our requirements for food sealing
The new size of potato chip cans is in place, providing you with a variety of choices in terms of craftsmanship quality and sealing solutions.
