PVDC/PE shrink bag,China no price supplier

The PVDC/PE shrink bag which the barrier layer is PVDC resin . It is a multilayer coextrusion material. It can be used for fresh beef , mutton, pork and Cheese , and can be used for processed meat.      

1. Physical Property Parameter
(1)OTR:  less than 20cm3/m2.24h.1atm.23.65%RH       GB/T1038-2000
(2)WVTR:less than 6g/m2.24h.1atm.23.90%RH            GB/T1037-1988
(3)Tensile strength :MD50MPa,TD30MPa;                     GB/T13022-1991
(4)Elongation at break:MD/TD 110%;                GB/T13022-1991
(5)Hot water shrink rate:MD40%,TD40%;     (90 water ,5 seconds)
(6)Heat-sealing strength:15N/15mm.     QB/T2358-1998(sample:straight line end sealed)

2. Appearance parameter
((1)Crystal point, carbon point: a small amount can be allowed, at most 2 carbon-points per 1m length.
(2)Scratch, bubble, dirt,stain can be allowed,but PVDC material itself sour taste and ozone smell generates while deal with radiation crosslinking.
(3)Sealing parts, non-virtual sealing phenomenon.
(4)wrinkle: a slight intermittent wrinkles can be allowed.

3. Advantages:
1) High oxygen barrier, slow germs breed, protect inside fresh meat  to be oxidized to go bad.
2) High moisture barrier, keep fresh meat water inside, reduce the fresh meat to lose the weight in store or conveyance.
3) High shrinking rate: make the bag cling with the fleshy surface and let it have a nice appearance. 
4) High odor barrier, maintain the original flavor
5) Irradiated film,it has higher tensile strength, puncture strength and abrasion resistance...etc. Its property is more than twice than no Irradiated film
6) Wide range of Shrink Bags Specification:                                                                
(1)Thickness : 50-70um
(2) Length:    100mm-1500m;   Length discrepancy:±5mm
(3) Width : 180mm-450mm;        Width discrepancy:±5mm:
7) Shape of sealed : straight line end sealed, curve end sealed , flank sealed.
