Shrink wrapping is an important packaging technique used by a variety of industries to protect products, bundle items, and create tamper-proof seals. While professional shrink wrap machines can complete the process quickly and consistently, you can achieve similar results without expensive equipment
Shrink wrap is a polymer plastic film that shrinks when heated to create a tight seal around the product. The process usually consists of three steps:
1. Wrap the product with shrink film
2. Apply heat to start the shrinking process
3. Allow the film to cool and set
1. Cut the shrink film to the desired size and leave enough space to wrap the product
2. Wrap the product loosely so that the seams overlap
3. Use the highest temperature of the blower to heat evenly
4. Keep moving the heat source to prevent scorching or uneven shrinking
5. Allow the wrapped product to cool before handling
Tip: For better results, rotate the product while heating to ensure even coverage.
1. Preheat oven to 300-350°F (150-175°C)
2. Place loosely wrapped items on baking sheet
3. Heat for 30-60 seconds and watch closely
4. Remove film once it has completely shrunk
5. Allow product to cool before handling
Warning: This method is only suitable for heat-resistant products and provide good ventilation. *
1. Bring the water to a boil
2. Briefly immerse the packaged product in the water (2-3 seconds)
3. Remove the film and allow it to shrink
4. Repeat as necessary to ensure complete coverage
While these methods occasionally work, in real projects, they have significant disadvantages compared to using a professional shrink packaging machine:
1. Inconsistent results: Manual heating often results in uneven shrinkage
2. Time-consuming: Each item needs to be handled individually
3. Safety risks: There is a risk of burns from high-temperature operations
4. Limited capacity: Not suitable for large-volume packaging
5. Professional appearance: Machine-wrapped items usually look more refined
If you are ready to upgrade from manual methods, we have the following models for you:
1. L-type sealer: Suitable for medium production, can form a neat L-shaped seal
2. Cavity sealer: Can completely wrap the product and shrink evenly
3. Tunnel sealer: Suitable for large-volume production lines
4. I-type sealer: simple, economical, and suitable for basic applications
