The wrinkle on surface is unavoidable when use LLDPE. So there need a special device to get a good one.
Note: enlarge the picture for clearly sense.
Suppose the products is for foreign market with shipping, you’d better adopt:
Packing material: LLDPE/PE + VCI paper/Knit Belt
First Layer LLDPE/PE
Second Layer VCI paper/Knit Belt
Suppose the products for local market. one layer packing is enough:
VCI paper/Knit belt
The roughly cost for packing material for horizontal orbital stretch wrapper with width 90mm:
VCI paper/knit belt: App. $2.47/kg and 110m/kg
LLDPE/PE film: App. $2.95/kg and 500m/kg
Full packing with 30% overlap need 40r, according the coils(OD800mm,ID400mm,width(900mm) which need 88m material.
So one packing would cost $1.98 (VCI paper/Knit Belt) $0.53 (LLDPE/PE)
