Universal property
◆ modular: This twines one of membrane packing biggestcharacteristics. With the aid of the thin film ultra strong windingstrength and the nerve, the product tie up fixedly compact, oneunit, causes the scattered light casting to become a whole, even ifthe product also does not have under the disadvantageousenvironment any with separates loosely, and does not have theincisive edge and the coherency, in order to avoid creates thedamage.
◆ primary protection: The primary protection provides theproduct the surface protection, forms one very lightly around theproduct, the protection semblance, thus achieves dustproof, againstoil, moisture-proof, the waterproofing, the security goal. Twinesthe membrane packing to cause the packing goods even stressespecially more importantly, avoids the stress creating the damageunevenly to the goods, this is the traditional packing way (tiesup, packing and so on pack, adhesive tape) to be unable to achieve.
◆ compression constancy: Stretches after the winding membranethe retraction strength carries on the product the winding packing,forms one compact, not to occupy spatial the unit whole, causesproduct various trays to wrap closely in the same place, butprevents in effectively the transportation process the productmutual dislocation and the migration, simultaneously may adjust thedrawing force may cause the flinty product to cling, causes thesoft nature product to reduce, particularly has the unique packingeffect in the tobacco industry as well as the textile industry.
◆ cost saving: Carries on the product packaging using thewinding membrane, may reduce the use cost effectively, uses thewinding membrane only then originally about box packing 15%, theheat contracts the membrane about 35%, about paper box packing 50%.Simultaneously may reduce the worker labor intensity, raises thepacking efficiency as well as the packing scale. principaladvantage the thickness is thin, the performance price outwardappearance is more transparent than good the , two-sided sticksnon-toxic, tasteless, secure good the easy to operate, efficiencyhigh anti-buffer intensity high good retraction rate anti-piercesagainst tearing performance good the vertically and horizontallystretch rate to reach 400% above
Is suitable profession widely to be suitable for the tradeexport, the can, food drink, the printing papermaking, thefire-proof material, the lignin floor, the cosmetics, thehandicraft, the adhesive-bonded cloth, the rug, the ceramicmechanical and electrical products, the computer, the communicationproduct, the books and periodicals, the electronic component, thefamily uses electricity, generation of labor original helpingmaterial, ceramic tile products and so on and so on buildingmaterials steel products, molding, wire rod, aluminum alloymolding.
