As Maripak Packaging Solutions we believe that the children are our future and all have equal rights to care, protection and education. However, we know that there are millions of children across the globe who do not share the same privileges their peers have access to. This is why we are a proud owner of “UNICEF Platinum Wings” working together with UNICEF in their quest to reach and support disadvantaged children.


Shrink wrapping is one of today’s most common secondary packaging techniques. It is widely used all around the world for packaging needs including maximizing shelf appeal, protection from external factors, bundling and multi-packaging to ease transport and storage, and last but not least tamper-proofing. This wide array of functionality makes it an excellent option for almost all industries from food to cosmetics or even boats and construction materials.

Why Invest In an Automated E-Commerce Packaging Solution?

Why Invest In an Automated E-Commerce Packaging Solution? Automated E-commerce packaging machines may seem quite costly at first sight. However, when  hidden costs of manual packaging is analyzed and compared to the savings from reduced labor costs, higher throughput, and improved productivity the investment pays for itself.

Shrink Packaging and Its Benefits

Shrink Packaging and Its Benefits Shrinking or Shrink Packaging is the process of wrapping any single product or group of products with plastic film, then applying heat via a heat tunnel so the film takes the shape of the product. It is commonly applied as secondary packaging. Without the application of heat, the packaging stays loose around the product and this is called polywrapping.

What is Shrink Wrapping?

What is Shrink Wrapping? Shrink wraps are made up of polymer plastic which tightly covers any object on the application of heat. A shrink machine is used to apply heat to these wraps. These are light in weight and can be used to wrap any material. The heavier versions of these wraps are used for industrial purposes. They are used to cover large equipment, large construction scaffoldings such as those used in the construction of bridges and buildings, helicopters, and other big vehicles. Shrink wraps are also used for storage purposes.

Packaging Machines

Packaging machines are now being used in every field and making our life easier in every way. Packing machines are large and small industrial machines that prepare all kinds of materials today, from dry food to detergent, which we use in our daily life, without any tangible touches and put them in our use.

Control Points of Quality Shrink Packaging

Control Points of Quality Shrink PackagingBefore starting to shrinking process, cut-wire or surface of the blade must be checked that they are smooth and clean. The plastic residue on the surface of the cut-wire or knife should be cleaned with the rubbing of the wastage film to hot wire. It should be never cleaned with the metal brush, knife, etc. The film must be cut before shrink and it should be checked that it is not open-torn by hand to check whether the film is cut and boiled properly. A certain amount will be left for the shrinking ratio during the shrinking. In proportion to the left ratio “package/package size”, a balloon is formed due to the air that wants to escape out. It must be confirmed that this balloon is formed and evacuation of the trapped air at the end of the shrinking should be observed. If the balloon does not form (and does not shrink at the end of the process), it means that the cutting/boiling process is not performed correctly. If the balloon suddenly disappears in the middle of the tunnel, the heat level may be high. If the air has not been evacuated even though the process is completed, the number of holes in the film may not be enough. Air evacuation in the balloon needs to be completed concurrently with the end of the time for proper Shrink packaging. The film must be properly punctured during the process or pre-drilled (perforated) film must be used in order for the air inside the balloon to be discharged correctly.Learn about shrink machines

The Importance of Perforation in Shrink Packaging

In shrink packaging, if the product will be sealed from all its four sides, the product will be fully closed and thus will be trapping air in it. When the package is heated, as the film will start shrinking, this trapped air will be compressed around the product yet as it will not be able to leak out, this situation will cause the film to swell like a balloon. If we do not give this air a chance to leak out, this balloon will often explode from a point on the sealed line.
