Packaging
The glued valve bag with a cross bottom (Hexagonal Bottom) is manufactured from multi-layer polyethylene (LDPE) film.
The film can be colourless or coloured according to the customer's request. Depending on the intended use, the material is modified with additives: anti-slip, anti-blocking, antistatic, antioxidant, and UV stabilisers.
The bag can be equipped with perforation or micro-perforation (for venting), anti-slip knurling strips, additional hot-melt seals, and a carrying handle.
Filling is carried out through a special valve, typically located in the upper part of the bag (except for models with a handle). The unique design ensures self-sealing after filling, and the bag assumes a stable, cuboid shape. Various valve types are available: internal or pocket valves.
High-quality flexographic printing on the bag's surface (including the top and bottom) is executed according to the customer's design. For dangerous goods, we offer the possibility of obtaining a UN certificate.
By embracing circular economy principles, we produce packaging that is 100% recyclable and can incorporate recyclates in its production, including PCR (Post Consumer Regranulate).
Benefits for the Customer:
- The use of a vent bag streamlines the packaging process without the need for additional sealing (welding) equipment. Filling the bag is quick, safe and clean.
- The vent bag is a very practical packaging solution, convenient for stacking on pallets and easy to use. Once filled, it takes the form of a cuboid, which allows for optimal use of space during loading.
- The use of vent bags guarantees convenience in transport, safety, and efficiency in high-bay storage.
- The vent bag is highly tear-resistant; the renewed thickness of the film minimises the risk of abrasion caused by the sharp edges of the packaged goods, while ensuring high resistance to external mechanical damage.
- The vent bag perfectly protects the goods placed inside, which, thanks to the tight closure technique used, do not escape outside, retain their properties and are protected against moisture, dirt, and dust. Certified (UN certificate) vent bags can be used to transport and store hazardous materials.
- We offer assistance in developing print designs and producing printing plates.
- We also provide advice on the selection of the type and size of vented bag, depending on the intended use of the bag and the characteristics of the goods to be stored in it.
Applications:
Plastic valve bags with a cross bottom are used for machine and manual packaging of loose and granulated products for many industries. The recommended method of filling the bags is to use so-called weigh-packing, which, in addition to automatically dispensing a strictly defined amount of goods, also shake them during packaging (for goods with variable bulk weight).
- In the construction industry: for packaging adhesives, fillers, bituminous compounds, sand, aggregates, etc.
- In the chemical industry: as ideal packaging for chemical fertilisers, plant protection products, salts, plastic granules and many other chemical substances in loose or granulated form.
- In agriculture and horticulture: for packaging seeds, mineral fertilisers, and garden gravel.
