Detailed Description
UKRBAGPACK LLC manufactures polyethylene liners for big bags with a thickness of 60 to 150 microns. The liner is an inner layer made of tubular PE film (HDPE/LDPE) that completely protects the container's contents from moisture, dust, and contamination. Using a liner is mandatory for hygroscopic materials: sugar, salt, chemical fertilizers, flour. We produce 4 types of designs: loose, gusseted (with side folds), form-fit (repeats the contours of the big bag), and with a suspended spout for automated loading. There is an option with a food-grade certificate and a heat-resistant type up to +80°C.
Design Variants
Standard loose liner
The classic option — a rectangular film bag placed inside the big bag. The cheapest and most common type.
Gusseted (with side folds)
Side folds allow the liner to fit more tightly against the walls of the big bag. Better volume utilization.
Form-fit
Repeats the shape of the container. Fixed to the loops of the big bag. Maximum efficiency — no excess material.
With suspended spout
The neck of the liner is attached to the filling spout of the big bag. Convenient for automated loading.
Applications
FAQ
When is a polyethylene liner needed for a big bag?
A liner is mandatory for hygroscopic materials (sugar, salt, fertilizers), fine powders, food products, and any cargo requiring protection from moisture or dust.
Which film thickness should I choose?
60–80 microns — for light bulk goods (grain, compound feed). 100–120 microns — standard for most tasks (fertilizers, sugar). 150 microns — for heavy abrasive or liquid materials.
Can the liner be used for food products?
Yes, we manufacture liners from food-grade polyethylene with the appropriate hygiene certificate. Suitable for sugar, salt, flour.
