The machine adopt anti-viscosity,high temperature resisting,thermostatic super fine aluminum-alloy sealing cutter.Adjusting precision of temperature and making bags length is super,the running is steady and dependable.It issuitable for film contraction packing in pharmaceutical, food,toothpaste,cosmeics,electron and toy industry. Five Reformation(Creative destgn): Ⅰ、The old model abopt single cycle hot air(it make the indoor temperature not even)the new mldel adopt dual-cycle hotair,it can form cross and rotary hot air and make the contraction room temperature even. Ⅱ、The whole machine adopt PLC controlling and the running is more steady and dependable. Ⅲ、The main material adopt stainless steel and meet GMP reauirement. Ⅳ、The tolerance of contraction and sealing and sealing tempperature is improved3℃ from 1℃ Ⅴ、The machine adopt all side door structure it is easy to maintain
