How to Reduce Waste in Shrink Wrapping: Solutions to Avoid Re-Wraps
In today’s packaging industry, shrink film is a key resource for ensuring protection, flawless presentation, and tamper-evidence. However, one of the most common issues on production lines is the occurrence of re-wraps: the need to repackage a product due to defects or errors. This leads to material waste, operational downtime, and reduced efficiency.
In this article, we examine the most common causes of re-wraps, how to avoid them with advanced technology, and what measures to take to maintain high-quality shrink wrapping.
What Are the Most Common Causes of Re-Wraps?
When a package needs to be redone, it’s often due to one or more of the following factors:
Incorrect film size: a bag that’s too wide causes excessive folds, while one that’s too tight may tear or seal unevenly.
Uneven film tension: a slipping reel or imprecise feed creates packaging defects.
Product misalignment: if the product isn’t centered, the sealing may be off-position.
Outdated machinery: worn or non-digital systems cannot guarantee the precision required for continuous shrink wrapping.
Why Choose a Continuous Side Sealing Machine?
Shrink wrapping machines are mainly divided into two types: L-sealers, which seal around the product in two directions, and machines with continuous side sealers, designed to work uninterruptedly along the product’s side.
The difference is significant: while L-sealers are ideal for small volumes and compact items, continuous side sealers offer higher productivity and can handle long products without longitudinal size limits.
Moreover, the continuous cutting system ensures a smoother workflow and a flawless aesthetic finish, with thin, regular seals along just one side of the package. It’s the ideal solution for industrial settings where speed and consistency are essential.
Packaging machines with continuous side sealing are the perfect solution for those seeking steady productivity, ease of use, and versatility when changing formats.
Accurate, consistent sealing even for long or irregularly shaped products
No interruptions in flow: ideal for continuous packaging cycles
Easy format changes thanks to electronic management
Reduced thermal loss and better energy efficiency
The continuous side sealing system eliminates product length limitations, ensuring impeccable appearance and a smooth, reliable packaging process.
Continuous Motion: More Flow, Fewer Errors
A continuous motion packaging line avoids the stop-and-go pattern typical of intermittent machines. The product flows without interruptions through the sealing and shrinking stages, minimizing errors caused by misalignments, slippage, or thermal variations.
This fluidity also allows you to manage more chaotic lines, with irregular spacing or mixed formats, while maintaining high efficiency and precision.
The Role of Shrink Film in Reducing Re-Wraps
The type of film used is crucial. Inadequate film can cause wrinkles, uneven shrinkage, or visual defects that require re-wrapping. To prevent this:
Choose films compatible with multiple package types to simplify operations and save material.
Use thicknesses appropriate to the product’s weight and volume
Control film tension using automated systems
Bag Size Matters: Why the Right Fit Is Essential
A bag that’s too wide leads to film waste and unattractive packaging; one that’s too tight may tear or misalign. Advanced automatic machines adjust bag length based on product size, ensuring precision and a professional look without waste.
Preventive Maintenance: Key to Operational Continuity
A well-maintained line is an efficient line. Some essential tips to prevent re-wraps:
Regularly clean sealing components
Check rollers, guides, and sensors
Promptly replace worn-out parts
Pactur’s modern automatic packaging machines drastically reduce the need for intervention, thanks to stable electronics, wire-free sealing systems, and integrated thermal management.
Which Industries Benefit Most from Reducing Re-Wraps?
Re-wraps can compromise efficiency in industries with high quality standards. Especially:
Pharmaceutical and nutraceutical
Food industry and baked goods
Cosmetics and personal care
Household goods and consumer products
Publishing and print materials
In these sectors, investing in a modern automatic shrink wrapper ensures less waste, higher output, and better product presentation.
How to Choose the Right Packaging Machine to Prevent Re-Wraps

Shrink Packaging and Sustainability: How to Package with Less Plastic and More Efficiency
In recent years, the packaging industry has undergone a major transformation, driven by growing environmental awareness and increasingly stringent regulations. In particular, shrink packaging—long appreciated for its protective effectiveness and high visual quality—is now at the center of a shift toward more sustainable solutions.
But what does it really mean to package sustainably? Is it possible to maintain high performance while reducing environmental impact? What are the eco-friendly alternatives to traditional shrink films? This article explores these questions with a technical and practical focus, looking at European regulations and the solutions offered by PACTUR.
🌍 Sustainability in Packaging: From Trend to Necessity
Until recently, sustainability in packaging was seen as a plus. Today, it’s a necessity. Consumers, companies, suppliers, and institutions demand more environmentally friendly packaging. This applies to every sector—from consumer goods to food, cosmetics to mechanical components.
Shrink packaging has often been criticized for its use of plastic, but it’s also one of the fields where significant innovations have emerged to reduce environmental impact.
PACTUR has taken a proactive approach, offering solutions that combine technical performance, energy efficiency, and environmental respect, without compromising packaging quality.
📦 What Is
Sustainable Shrink Packaging?
Sustainable packaging:
Uses fewer and/or recyclable materials
Is produced with low-energy machinery
Minimizes waste during the packaging process
Optimizes the packed product volume (e.g., for transport)
Complies with current environmental legislation
In the case of shrink packaging, the main strategies are:
Using thinner but resistant films
Adopting recyclable or recycled-content materials
Optimizing the shrink process with efficient machines
Custom-designed packages to reduce excess material
♻️ Materials: Eco-Friendly Alternatives to Traditional Films
The type of film used is crucial. Common materials in shrink packaging include PVC, POF (polyolefin), and PE (polyethylene). Today, more sustainable versions exist that reduce plastic use without sacrificing quality and protection.
PVC: Still Common
PVC film is appreciated for its shine and rigidity but is not very recyclable and unsuitable for some applications. It may release harmful chlorides when burned. PACTUR recommends its use only in specific cases and promotes more eco-friendly alternatives.
Polyolefin(POF): Versatile and More Sustainable
Polyolefin is a shrinkable, transparent, and flexible material. Some manufacturers now offer eco-friendly versions of POF with reduced thickness (e.g., 12 or 13 microns instead of the usual 19 or 25) and up to 30% recycled content. These films provide the same performance with less plastic.
Polyethylene(PE): The King of Recyclability
PE, mainly used for sleeve wrappers (not transparent but strong films), is fully recyclable and can be regenerated multiple times. Pactur integrates recycled PE films in its sleeve wrapping machines, with excellent results in terms of strength and protection.
Compostable and Bio-Based Films
In some sectors, compostable or plant-based films (PLA, corn-derived) are emerging. These materials are still costly and have technical limitations, but represent a promising development area. Pactur monitors this trend carefully for future integration.
🔬 Reducing Thickness While Maintaining Performance
One of the strongest trends in sustainable packaging is reducing film thickness. Thanks to more advanced extrusion technologies, it’s now possible to produce 12 or 13-micron rolls that perform like 19 or 25-micron ones.
PACTUR regularly tests these materials on its machines and promotes the use of ultra-thin films to cut plastic usage by up to 40% compared to traditional options.
The benefit is not only environmental: thinner films reduce material cost, packaging weight, and optimize logistics and transport costs.
📜 European and Italian Regulations: What’s Changing in Packaging
The European regulatory framework on packaging is evolving. Leading the change is the Packaging and Packaging Waste Regulation (PPWR), which aims to replace Directive 94/62/EC. The new regulation targets:
A 15% reduction in packaging waste by 2040
Phasing out unnecessary packaging (e.g., empty or oversized)
Ensuring all packaging is recyclable by 2030
Introducing mandatory minimum percentages of recycled content in plastic films
For packaging manufacturers and users, this means redefining materials, formats, and processes. Italy’s Circular Economy Action Plan (D.Lgs. 116/2020) also supports this direction. Moreover, CONAI already applies differentiated environmental contributions based on recyclability: those using easily recyclable materials pay less.
PACTUR assists its clients with this as well: selecting the right film is no longer just a technical matter—it’s also an economic and regulatory decision.
⚡ Energy Efficiency in Packaging: A Key Factor
The sustainability of packaging is not only about materials. Energy consumption also plays a key role. An efficient shrink wrapping machine can significantly reduce the environmental impact of each cycle.
Pactur shrink wrapping machines are designed to:

From pinholes to burn out, find out what your shrink wrap is telling you.
Nothing is more satisfying than a perfect shrink wrap when the package comes out of the shrink tunnel. Experienced operators know that when, on the other hand, a package comes out with imperfections, the result itself provides clues on how to adjust the system configuration to correct the problem. If you’re having problems with shrink film, all you need to do is “read” these clues about the film.
The article “Problems with Shrink Film” explains the potential underlying cause of six of the most common film problems, including burnout and pinholes, as well as the configuration adjustments that usually resolve the issue.
Three variables that affect the results of shrink wrap
Prima di esaminare questi sei problemi comuni, è importante comprendere le variabili che influenzano il processo di retrazione. Queste tre variabili sono: dimensione del sacco, evacuazione dell’aria/perforazioni e temperatura o velocità del tunnel.
Diamo un’occhiata a come queste tre variabili influenzano il film.
Bag size
During the shrinking process, the bag must be large enough to allow the film to peel away from the product and collapse just before exiting the tunnel chamber. If the bag size is too tight, the film will contact the product too soon, resulting in fish eyes or crow’s feet. The film must first swell from the product and then collapse.
Air evacuation (drilling)
Bleeding the air out too quickly does not allow the film to inflate properly, resulting in wrinkles, crow’s feet or fish eyes. Bleeding the air out too slowly will cause bubbles, a cloudy film and potential burns. Placement of Perforations: Checking which part of the bag holds air the longest can help control shrinkage. The most critical element for the appearance of the package is the control of the air evacuation!
Tunnel temperature and speed
For a good appearance of the package, it must spend 3 to 4 seconds in the tunnel chamber. The size of the tunnel depends on the productivity. Always adjust the speed and temperature of the tunnel conveyor so that the film balloon collapses just before exiting the tunnel chamber.
Six common shrink films problems
Now that we have an understanding of the three most important variables in the shrink process, let’s look at how an incorrect machine or film setting can be seen in the final package, the most common cause, and how to correct the problem by adjusting the set up.
Burnt problems with shrink wrap
BURNOUT: Holes or cracks in the film outside the weld line
COMMON CAUSE: Insufficient air exhaust
ADJUSTMENT: Add some perforations so that the air escapes more quickly
Cloudiness
CLOUD: Film is foggy/blurred
COMMON CAUSE: The tunnel temperature is too high
ADJUSTMENT: Adjust the temperature or try speeding up the conveyor belt. You may also need to add some perforations.
Crow’s feet
CROW’S FEET: Wrinkles at the corners and near the edges
COMMON CAUSE: Inadequate bag size: bag is too small or has too many perforations
REGULATION: The bag should inflate away from the product during the shrinking process. Adjust the size of the bag and remove some of the perforations.
Dog ears
DOG EARS: curled film protruding at the end of the seal
COMMON CAUSE: incorrect bag size, too many perforations, time and temperature in the tunnel
ADJUSTMENT: Make adjustments to ensure the bag has 3 to 4 seconds of dwell time inside the tunnel chamber.
Fish eyes
FISH EYES: Rounded spots near the edges
COMMON CAUSE: Inadequate bag size and/or too many perforations
REGULATION: The bag should inflate away from the product during the shrinking process. If there are too many holes, the bag won’t inflate properly, or if the bag is too small, it will contact the product too quickly. It will help to adjust the size of the bag and remove some of the perforations.
Pinholes
PIN HOLE: Small holes along the gasket
COMMON CAUSE: An installation problem where there is too much tension on the film during the sealing process
ADJUSTMENT: Try making a bigger bag and loosening the tension on the film.
