Industrial Paper Valve Bags Supplier - Ulinkpack
A paper valve bag is a type of industrial packaging used for efficiently storing and transporting powdered or granular materials. These bags are commonly found in industries like construction, agriculture, chemicals, and food production. Let’s break it down a bit:
Key Features:
Materials
Made of multiple layers of kraft paper, often with an optional plastic liner for moisture resistance.
Valve Opening
There’s a small opening (the valve) on one corner of the bag. This allows for quick filling using specialized equipment, and the valve seals itself when the bag is full.
Sealing Options
The valve can be self-closing, heat-sealed, or ultrasonic-sealed, preventing leakage.
Industries That Use Them:
Construction
for packaging cement, mortar, grout, and other dry mixes
Food
for packaging flour, starch, and sugar
Chemicals
for packaging pigments, resins, and powders
Customizable
Personalized items available
Advantages:
- Fast filling and sealing reduce labor and equipment costs.

- Environmentally friendly — paper bags are often recyclable and biodegradable.
