Batch-Inclusion Polyethylene Block Bottom Valve Bag
These durable valve bags, made from virgin low melt polyethylene resin, are designed to be added directly to a mixture during manufacturing, eliminating the need to open and empty the bag. The bag melts and its contents disperse into the mixture, minimizing personnel exposure to hazardous materials. These plastic valve bags are an ideal choice for chemicals used in the paint, rubber, and tire manufacturing industries, such as Carbon Black and Titanium Dioxide.- Bag melts and its contents disperse uniformly into mixture
- Eliminate product loss and contamination
- Minimize worker exposure to hazardous materials.
- Custom formulated film has a melt point of 100C-108C
- Ensures consistent batch quality
Valve Types
Standard Internal Valve
The most economical valve option, a standard internal valve is constructed by gluing a strip of woven poly material into the valve opening to make it stronger and more sift resistant.
Tuck-In Sleeve
This type of valve is folded and tucked in manually after filling. An optional thumb notch can be added for easier use during machine packing.
Sonic Seal Sleeve
This is an outer poly sleeve extension used for ultrasonic hermetic sealing. The sleeve is constructed of spunbond polypropylene or polyethylene.
Industry Applications
Plastic valve bags are used across a diverse range of industries that work with dry, flowable materials.
Construction
Plastic valve bags may be used to package cement, mortar, grout, and other dry mixes.
Chemicals
Fertilizers, resins, powdered chemicals, and various industrial compounds can be packaged in plastic valve bags.
Agriculture
Sift-resistance makes these bags a good choice for agricultural products like powdered supplements, feeds, and agricultural additives.
Food Industry
Food packagers use valve bags for flour, dry food ingredients, and various food additives.
Minerals
Plastic valve bags are a good option for packaging dry mineral powders.
