不同之处就在于一般的制袋机是底封，二热切封边的制袋机是封两边，一般的制袋机是封桶装的薄膜，二热切封边的是直接片材卷筒经过对折然后把两边封主，一般边封做的都是服装袋或则面包袋等产品主要是制造PP或则opp等材料的袋子。
The difference is that the general bag-making machine is bottom-sealing, the second hot-cutting edge-sealing bag-making machine is to seal both sides, the general bag-making machine is to seal the film in barrels, and the second hot-cutting edge-sealing machine is to fold directly the sheet drum and seal both sides. Generally, the side-sealing products are clothing bags or bread bags, which mainly make PP or OPP Bags and other materials.
