Shrink Wrapping Machine

A machine that uses heat to shrink a film of plastic (shrink film) tightly around a product or group of products, providing protection, tamper evidence, and often improved presentation.

Types of Shrink Wrapping Machine

Manual Shrink Wrappers: 

Hand-operated sealers and heat guns for low-volume use.

Semi-Automatic Shrink Wrappers:

Requires an operator to load products and/or initiate the sealing cycle.

L-Bar Sealers: Create an "L" shaped seal.

Side Sealers: Continuously seal along the side of the product.

Automatic Shrink Wrappers: 

Fully automated, integrating product feeding, sealing, and shrinking.

Continuous Side Sealers: High-speed, continuous motion.

Flow Wrappers with Shrink Tunnels: Combines horizontal form-fill-seal with a shrink tunnel.

Bundling Machines: For wrapping multiple products together.

Shrink Tunnels: 

Ovens designed to apply controlled heat for uniform shrinking of the film.

Applications in Various Industries:

Food & Beverage: Packaging baked goods, frozen foods, multi-packs of bottles/cans.

Cosmetics & Pharmaceuticals: Tamper-evident seals, product protection.

Retail & Consumer Goods: Packaging toys, stationery, software, DVDs.

Printing & Publishing: Wrapping magazines, books, promotional materials.

Industrial: Bundling parts, protecting components from dust/moisture.

Technology: 

PID temperature controllers for precise heat, conveyor systems (mesh or solid), film tensioning mechanisms, precise cutting and sealing blades (hot knife, impulse sealer), automated product feeding, PLC control, safety features.

Material Selection Considerations

• Frame: Powder-coated steel or stainless steel for durability and hygiene (especially food industry).
• Heating Elements: Nichrome wire or similar resistance heating alloys for durability and consistent heat.
• Conveyor Belts: Silicone, Teflon-coated mesh, or other heat-resistant materials.
• Sealing Blades: Teflon-coated alloys for non-stick properties and clean seals.
• Insulation: High-temperature insulation for shrink tunnels to prevent heat loss.
• Electrical Components: Heat-resistant wiring, robust motors.
