Valve bags

Polyethylene box bags

Polyethylene box bags are widely used in production for the packaging of various bulk and granular materials.

Color, printing, and technical specifications are agreed individually with the customer.

Important: the bags we offer are made from multilayer film. They are much cheaper due to the smaller mass, but at the same time stronger.

Idea-com specialists will provide you with comprehensive technical support in the development of project documentation. If necessary, we will make test samples, and we can also attend test trials.

Application area:

  • packaging of mineral fertilizers;
  • packaging of granules, for example, polyethylene, PVC;
  • packaging chemicals such as calcium chloride, rubber, carbon;
  • food packaging, eg vegetable concentrates, salt, sugar;
  • packaging of flour, cocoa, animal feed;
  • packaging of bulk materials such as sand, cement, gravel, etc.

At the request of the customer, bags are given additional properties:

  • resistance to UV radiation;
  • puncture resistance;
  • perforated surface for air outlet;
  • embossed surface to reduce slip;
  • painting in any color, as well as printing up to 6 colors.

The materials from which the bags are made do not emit toxic substances and do not have any effect on the human body upon contact. This means that they can be used without additional precautions. The bags do not form toxic compounds in air or water in the presence of other substances under ambient conditions.

Polyethylene box bags that we offer can be operated at temperatures from minus 40°C to plus 60°C. When storing and transporting at sub-zero temperatures for more than a day, the bags must be kept before further use for at least 24 hours in a dry room at a temperature of (5-25) ° C.

Box bags can be filled both manually and with the help of special filling machines and devices.

When packing products in bags with a valve, air can be removed from it in the following way:

  • vibration and pumping out of air when filling the bag;
  • perforation near the valve;
  • pre-compression of the packaged products using a vibration device;
  • removal of air from the bag on the crimping rollers after packaging.

Products packed in box bags should be stored in dry warehouses. Bags must be stacked on pallets. Do not store bags in a vertical position.
