POF
heat plastic protective shrink film for food With
excellent clarity, a strong, biaxially orientated, heat shrinkable
polyolefin film. The film maintains a balanced and stable shrink
through the heat tunnel. It is a soft flexible material which is
suited to both semi automatic and fully automatic shrink
lines. The material is a multilayer co-extrusion which
enables high sealing speeds at lower temperatures, and it can be
recycled with Polyethylene.Product Feature Environment
protection ,harmless and nonpoisonousTight sealing and perfect
welding performanceHigh shrinkage ratioAirproof packaging, dust and
moister resistanceLight weight and excellence in flexibility and
tensile strength, even thickness High transparency and

temperature, aging resistance. Excellent thermal sealing and
easy wrappingProduct ApplicationPolyolefin shrink film is widely
used to shrink wrap packages of foodstuffs, medicines, drinks,
electronic & electrical products and toys. Its outstanding shrink
ability makes it the first choice when heat shrinking products &
packages.Product PropertiesAvailable

effective control the thickness of film.. 32--36bolts set on the
Die head , worked with NDC thickness gauge, reduced the error of
film's thickness to ±1mic. Water colding outside
the tube blank and wind colding inside the tube blank together ,
can assure tube cold quickly .That is the main
reason why our film's clarity is better than others.Two 5 layers
2400mm JINMING lines and Three 3layers 2200mm JINMING lines can
make our films have wide range to select on their

Gloss..WHAT DOES POF MEAN? POF is an abbreviation for polyolefin and generally refers to heat shrinkable shrink film. WHAT EQUIPMENT IS NEEDED TO SHRINK POF? Various machines are used, from simple heat guns to conveyor driven heat shrink tunnels. The product, volumes and purpose dictate the appropriate solution. HOW IS THE SHRINK FILM SEALED? There are many ways of sealing the pack from a simple bar sealer, an L sealer and on to the automated machines likecontinuous side seal and flow wrappers. WHAT IS A CENTREFOLD ROLL? Shrink film is often folded and then rolled so that when the roll is unwound, it has an open and a closed side. This is done to improve the packing efficiency when using an L sealer. WHAT IS SINGLE WIND OR LAY FLAT? This is simply a roll of film wound in a single layer. This is used for flow wrapping machines or many other automated machines. CAN I PRINT ON POF? The simple answer is yes. It is advisable to do this on volume lines, though. WHAT TEMPERATURE DOES POF SHRINK AT? Generally POF shrinks at around 150 degrees C. It is important to understand that the heat of the tunnel, the length of the tunnel, the speed through the tunnel and the type of pack being covered all need to be controlled to get the perfect shrink. DO I NEED SPECIAL VENTILATION FOR POF? Not because of the film. The ventilation needs to be appropriate for the heat tunnel though. HOW THICK MUST THE SKIN PACK FILM BE? Generally speaking, the heavier the item being packed, the thicker the film.
