The Evolution of Hermetic Sealing in Packaging
In the realm of bulk packaging, Heat Sealed PP Woven Bags have become indispensable for industries requiring absolute product protection. This sealing methodology, which employs precision-controlled heat bars (160-190°C temperature range), creates molecular-level bonds between PP layers that surpass traditional sewn seams in both strength and integrity. At VidePak, we’ve perfected this technology across 16 production lines, each capable of producing 1,200 flawlessly sealed bags per hour while maintaining ±0.5mm seal width consistency.
