Multi-chamber IV bag is the separate storage of different medical content in different subchambers by welding during production, storage and transportation. For the welding strength of multi-chamber IV bag, isolated contents during storage and transportation must be maintained. Therefore, multi-chamber welding process control is the key procedure in the whole production. Welding is determined by three indexes: temperature, time and pressure. How to control this index successfully is a focus for multi-chamber IV bag manufacturers. [...]

Heat seal strength is one of significance properties  for  BOPP Cigarette film quality control. BOPP films require high heat seal strength and wider heat seal scope by the cigarette industry, so as to improve packing speed and proper operation. However, if the heat seal temperature is higher, it would lead to wrinkle because of increased BOPP film shrinkage. Therefore, proper heat seal temperature should be chosen so as to avoid unstable heat seal, wrinkle and [...]
