Application

PVC heat Shrinkable Sleeve / Film / Tube is used in packaging Industry for shrink wrapping since it has so many good properties and economical. The properties of Heat shrinkable PVC sleeve can be listed as follows :

• Relatively low cost.
• Excellent chemical resistance.
• High clarify and gloss.
• Excellent Printability.
• Unaffected by Humidity ( Non - fogging ).
• Good Dimensional stability.
• High stretch, Permitting wrinkles free wrapping.
• Good flavor Barrier.
• Long shelf life without becoming brittle.
• Low permeability to Oxygen, Nitrogen and Carbon - Di - oxide and water vapor
• Excellent Thermoforming Characteristics.
• High Stiffness Modules.
• Wide choice of colour shades.
• Better Tear and Impact Properties.
• Excellent Insulation Resistance.
• Excellent Corrosion Resistance.
• Excellent Break down Voltage coupled with mechanical strength
• Good Abrasion Resistance.

Various Applications can be classified based on the properties of Heat Shrinkable PVC

Transparency :

Transparency of heat shrinkable PVC sleeve has attractive aesthetic appeal. Since the film can be printed on either side, it can be used for packing Household Articles, Novelties, Cosmetics, etc.

Tear Strength :

Due to such superior mechanical properties wall thickness of the sleeves can be greatly reduced. The thin wall construction of the sleeve makes it flexible and facilities complete, quick and efficient shrinkage. It also gives high degree of transparency, which is ideal for applications where legibility of message printed on the cover is important.

Non - Polar surface :

PVC sleeve with non - polar surface is an ideal material for different types of printing such as screen printing, Offset printing, Rotogravure printing, etc. This printed transparent or opaque sleeve can be used for covering cardboard, Glass, Metal or Plastic containers or Articles.

A transparent sleeve on the body of the container insets and protects the label, eliminating need for individual carton. A substantial cost reduction is effected and inventory requirements are simplified.

Excellent Corrosion Resistance :

PVC sleeve can be used to cover the zinc containers in dry battery cell, to provide protection to outer metallic or cardboard cover. Inside PVC sleeve not only protected the cell but also the expensive equipment such Transistors, Tape Recorders, Flashgun, by providing complete protection against corrosion.

It can also be used as corrosion resistant or rust resistant packaging for polished steel tubes, rods and profiles, during storage and handling.

Excellent Insulation Properties :

PVC sleeve an ideal insulating material for Capacitors and parts which are used in large quantities in radios, Television sets, Tape Recorders and other electronic equipment's in Microprocessors, Computers, Drives, etc.

Excellent Break - Down Voltage :

PVC sleeve are used for covering Bus - Bar conductors, Wiring, Wire Heads, Cable Terminals and joints etc.

Resistance to acids, Alkalis and Chemicals :

PVC sleeve can be used to protect to pipeline in Chemical Industry; Cables for anchorage of ships, The sleeve can save costly equipments from damage due to corrosion at very marginal cost.

Abrasion Resistance :

PVC sleeves are used in hydraulic lines and fittings where good protection against Abrasion is required. PVC sleeve forms a high mechanical seal over the fitting and Renders necessary protection.

Special Application - Pilferproof Packaging :

Indian Industry is facing serious problems of adulteration and inferior qualifies of goods are sometimes marked under famous brand names. PVC sleeve can act as a security device in the form of closer to new concept to Indian packaging industry.

It can replace conventional material like Paper, Aluminum Foil, Polyethylene etc. used for sealing Bottles, Cans, Food, Oilcans, LPG gas cylinders Valves etc.

Miscellaneous Applications :

PVC sleeve is widely used in mechanical engineering Industry. Bearings can be packed to protect them from pilferage and corrosion. Hand Tools and cutting Tools can be protected against rust and corrosion. It also facilities handling and transportation.

Coloured PVC sleeves protects central rod of TV Antenna against the effect of atmosphere corrosion and rusting, also it increases sales appeal of TV antenna.

PVC sleeve makes it tamperproof when used as a covering for finished dry battery cells and also improves the quality and performance.

If printed sleeve is used, it gives security seal-cum-label after shrinkage. The attractive and protective covering gives the impression of cleanliness to the article. This security seal is unaffected by most of the chemicals. Due to multicolour printing it improves advertising and pilfer unaffected by most of the chemicals. Due to multicolour printing it improves advertising and pilfer proofing effect. It protects the contents by preserving flavor and freshness. It particularly protects sensitive fragrances, which have a tendency to evaporate. In addition, all Capillary leaks of liquid are prevented.
