Applications:
Paper bags are tear-resistant, heat-tolerant, and capable of carrying loads over 50 kg. Can produce heavy-duty valve sacks or open-mouth square-bottom bags for cement, mortar, putty powder, gypsum, and other heavy construction materials.
Dimensions:
Tube width: 350–680 mm; Length: 500–1350 mm—fully covers standard cement bags and specialty mortar bag requirements.
Bottom pasting machine supports external/internal reinforcement lengths of 100–520 mm, significantly improving impact resistance and stack stability.
Speed:
Tube forming speed up to 150–350 tubes/minute.
Sealing Options:
Double-row dot gluing + center seam gluing ensures bottoms remain intact under loads exceeding 50 kg.
Layers:
Can produce 4-layer kraft paper + PE film structures with high bursting strength.
Equipment Advantages:
Supports paper rolls with diameters over 1.2 meters, reducing roll-change frequency—ideal for continuous production in the construction materials industry.
