The negative impact of polyethylene waste on the ecology of the environment makes us think about restrictive measures for the use of this type of packaging material at the state level. In some developed countries, similar laws have already been put into effect. According to https://upack.ru/, this gave rise to the introduction of new technologies, including it should be noted that it is very effective, it involves the use of reusable plastic bags with a ZIP-LOK fastener for the sale and storage of a wide variety of products:
- Perfumes, hygiene items or cosmetics.
- Medicines or consumables.
- Food or documents.
Quite simple and easy to use, the fastener can reduce the consumption of packaging material by an average consumer tenfold. At the same time, it provides sufficient tightness to store and protect the contents from various environmental factors (humidity, ultraviolet light, dust, insects or bacteria).
The main types of ZIP-LOC fasteners
The principle of operation of the ZIP-LOK fastener is based on the elasticity and resilience of plastic material. The edge protruding along the entire length of the opening part of the package, falling into the corresponding grooves, after mechanical action is fixed in them with sufficient tightness and reliability. There are 2 main types of fixing grooves:
- Symmetrical - refers to the budget execution format due to its simplicity. It does not allow adjusting the force of opening the lock from both the outside and inside.
- Asymmetric - the inner part of the groove has the shape of a kind of hook, which makes it possible to more reliably fix the protrusion that falls into it.
Convenience of using a zipper tape is that the lock, after applying a little effort, opens only from the outside. Internal stresses, for example, as a result of moving the stored products during transportation, are not possible.
You can get more complete information about the types and forms of packages equipped with ZIP-LOK locks using the website of the company that manufactures them, including for individual orders in small batches.
