Overwrapping machines can process PLA at a pace of 30 to 110 packets per minute. The outcome, an eco-conscious, shiny wrap, pleases the eco-minded customer.

Polyethylene

Polyethylene presents a blend of versatility and value. Its tensile strength stands between 1700 to 3200 psi. The light transmission of polyethylene is 80% to 90%.

Overwrapping machine rates for polyethylene span from 20 to 120 packets per minute. The resulting package offers a glossy, engaging finish.

Specialty Films

Specialty films, the customized solution, cater to unique needs. Their tensile strength varies widely, typically within 3000 to 7000 psi. The transparency scale ranges from 60% to 95%. Overwrapping machines can process specialty films at 20 to 130 packets per minute. The final package boasts a customized, high-gloss finish.

Choosing the Right Overwrap Material

Product Type

Every product asks for a unique overwrap. For food, a polypropylene (PP) film is widely chosen. Notably, about 60% of the global market prefers this.

PP film ensures your product stays safe and fresh. Conversely, cosmetics demand a cellophane wrap for its glossy finish. An astounding 80% of makeup companies use cellophane for overwrapping.

Material Cost

The cost of overwrap materials varies significantly. For instance, PP film costs around $1.2 per square meter. On the other hand, cellophane is slightly pricier, at approximately $1.5 per square meter. These figures account for roughly 20% of the total packaging costs.

Environmental Impact

In an age of sustainability, the environmental footprint is critical. Cellophane is 100% biodegradable, reducing landfill waste by 70%. PP film, while recyclable, takes up to 400 years to decompose.

Machine Compatibility

Compatibility with the overwrapping machine is paramount. The average overwrapping machine handles films between 20 and 30 micrometers thick. Around 90% of overwrapping machines support both PP film and cellophane.

Visual Appeal

An appealing overwrap drives sales. Cellophane is known for its gloss, enhancing product appearance by up to 50%. PP film offers a clear view of the product, boosting customer trust by about 30%.

Customer Preference

Over 70% of customers express a preference for clear overwrapping. Notably, the preference for biodegradable materials has seen an increase of 50% in the past five years. Brands must balance these preferences with practical considerations.

Shelf Life

The right overwrap extends product shelf life. A PP film can extend shelf life by up to 25%. Meanwhile, cellophane offers a moderate extension of about 15%. Both materials provide an effective barrier against external factors.

Storing and Handling Overwrap Materials

Handling overwrap materials needs great care too. During transport, care must be taken to avoid damaging the outer layers. Keep them away from sharp objects. Remember, damage can cause defects in the finished product.

As for the overwrapping machine, the role is crucial. It uses these materials to wrap products with precision. Speeds can vary, but modern machines can reach up to 300 packages per minute. Yes, you heard right, 300!

This machine’s adjustments are equally vital. The tension settings for the film should be set just right for a flawless overwrap.

Mastering these parameters ensures a quality product. It’s a truly perfect package, every single time. Remember, good practice in storage and handling, plus precision in machine settings, equals packaging success.

Conclusion

Overwrapping machines are workhorses of the packaging industry. With a speed of 300 packages per minute, efficiency soars. Each wrap is precise and bubble-free.

Thus, for neat, tight packaging, trust overwrapping machines. Your packaging needs are safe in their mechanical hands. Remember, perfection is their promise. For more support, contact SAINTYTEC!
