Overview
Shrink wrappers are machines that allow shrink wrapping plastic on products and packaging in an automated, semi-automated or even manual way. They are also known as shrink wrap machines.
The shrink-wrapping process is one of the most common packaging techniques. It is used at the end of the production line to protect products.
Most commonly these large machines are part of packaging lines in logistics centers and factories, although they can also be used individually.
Once the product is shrink-wrapped, a heat sealer is used, which uses heat to close the open ends of the plastic.
Once this step is completed, the package must go through a shrink tunnel or a heat gun if the process is manual. Here, heat is applied so that the plastic that surrounds the product contracts and reduces to the particular dimensions of the product.
In this way, the product is encapsulated in a plastic film that is firmly adhered to it.
To understand the typology and operation of these machines, it is important to know that the shrink-wrapping process requires the execution of two major tasks:
- Sealing to close the plastic that wraps the merchandise
- Shrink-wrapped to shrink and adhere the plastic to the product
For these two functions there are manual, semi-automated or fully automated solutions. And depending on this, the type of shrink wrap varies. Likewise, it is possible to purchase machines that carry out only part of the process (sealing or shrink-wrapping) or integrated systems that carry out the entire process with a high level of automation. All this determines the price of the shrink wrapper.
The choice of one or another model of shrink wrapper will depend on each project. Some of the variables that influence the decision are the type of production, production volumes, level of automation required, product characteristics, logistics systems currently in place, efficiency goals, costs, etc.
In this way, the automatic shrink-wrapping machines and integrated systems are designed for projects with high production volumes on an industrial scale. Where, in addition, efficiency and cost reduction are sought to achieve high yields.
For smaller productions, manual or semi-automatic shrink wrappers can be used. In these cases, an operator participates to a greater or lesser extent during the shrink-wrapping process.
manual shrink wrapper
With the manual shrink -wrapping machine, the entire shrink-wrapping process is carried out with the intervention of an operator for each of the phases. Normally, this type of machine includes sealer, heat gun and coil holder.
In these cases, it is the operator himself who wraps the product in shrink plastic and places it in the machine to close the ends with the sealer. And once it's ready, he applies heat to the package with a shrink gun so that the plastic completely conforms to the product.
It is a versatile and economical solution for small productions. In addition, its handling is simple.
semi-automatic shrink wrapper
Semi - automatic shrink wrappers require the participation of an operator, although to a lesser extent than in the case of manual ones.
In general, the operator covers the product with the plastic and introduces it inside the machine, where it is sealed and shrink-wrapped. So that the person only intervenes at the beginning of the process to place the product and at the end, to remove the already wrapped product.
What are shrink wrappers for?
The shrink-wrapping or shrink-wrapping machine has the objective of packaging or wrapping a product using shrink-wrapped plastic or thermoplastic film. The word shrink comes from shrinking, which means packaging with a transparent film that shrinks (by applying heat) adapting to the shape of the package.
Various industries use these systems to protect their products. It is an ideal technique for wrapping cosmetics, technology, food, books, boxes, bottles, etc.
