HEAVY DUTY SHIPPING SACKS

What are Polyethylene Heavy Duty Shipping Sacks?

PE Heavy Duty Shipping Sacks are used for a broad range of applications in the food, chemical and pharmaceutical industries. They are a time- and cost-saving packaging solution and enable high product protection. For branding recognition, the bags can be printed for individual requirements.

Three different technologies are used for Polyethylene Heavy Duty Shipping Sacks:

FORM, FILL, AND SEALING packaging lines

The form fill sealing technology (FFS) is an automated assembly-line product packaging system. The plastic bags are assembled out of a flat roll. At the same time preformed bags are filled with powder and/or granule product and the filled bags are sealed.

Valve filling

The valve bags are placed on in-line spouts and filled to the desired weight; afterwards the filled bags are sealed.

Open mouth

The open mouth bags are closed on one side of the tube, either by sewing or by gluing. An automated machine fills the pre-formed bags to the desired weight; afterwards the filled bags are sealed.
