How to choose a heat shrink tunnel machine?

What is a heat shrink tunnel machine?

The heat shrink packaging machine mainly uses heating as the principle to heat and shrink the film wrapped on the surface of the item, thereby packaging the item.

Advantages of heat shrink packaging machine.

1. The heat shrink tunnel machine can provide tight, transparent packaging, making the product more beautiful and marketable.

2. The packaged items can prevent moisture and pollution, and have certain buffering properties to protect the products when subjected to external impact.

3. Heat shrink packaging uses a large shrink film to package a variety of foods or other commodities together, which can prevent the product from being dismantled or stolen, and also facilitates transportation.

4. shrink film costs are relatively low and cheap, which helps reduce packaging costs.

Heat shrink machines are suitable for wrapping products in food, cosmetics, medicine, chemical, and other industries. Now, heat shrink packaging machines have occupied a large market in the industry and are favored by many manufacturers. Its powerful performance characteristics can greatly reduce packaging costs, help factories save energy losses, and enhance product image. So, how should manufacturers choose a suitable heat shrink packaging machine?

How to choose a heat shrinking machine?

1. Consider the film material

We need to understand the film material for shrink packaging and how to transport the product after shrink packaging. You can choose a relatively thin film material if you want to pack the shrinked items into a box. If you’re going to ship it directly after shrink packaging, consider choosing a relatively thick shrink film material.

2. Determine the packaging film

 Generally, there are three types of packaging films: POF, PE, and PVC. Generally speaking, PE film is very thick and usually used in beverages. POF and PVC are suitable for cosmetics, gift boxes, mobile phone boxes, and other items.

3. Determine the packaging form of the item

The packaging form of the item needs to be determined in advance. Generally, shrink packaging machines come in two packaging types: fully closed and Sleeve-type heat shrink machines. Completely enclosed, such as a cosmetic box. The shrink sleeve machine has small openings on both sides and is usually suitable for drinks, mineral water, beer, etc.

4. Determine the size of your items. 

Different heat shrinkable film packaging machine models have different sizes of shrink tunnels, so you can choose the one that suits you after determining your size.

5. Choice of semi-automatic or fully automatic type

Choose a semi-automatic or fully automatic heat shrink packaging machine. Semi-automatic heat shrinkable film packaging machines generally have only one shrinking machine. For fully automatic heat shrinkable film packaging machines, there is a sleeve sealing and cutting machine in front. The main function is to sleeve the film. Generally, if the output is not large, you can use a semi-automatic one. , if the output is large, you can choose a fully automatic shrink wrap machine.

6. Check the shrinkage effect. 

Carry out relevant tests to see if the effect is satisfactory.

7. Heating method. 

The heating methods of shrinkers are different. Some are heated by quartz tubes, and some are heated by steel tubes. The former is cheaper, and the latter is more expensive. However, the quartz tube is the worn part of the shrinker and is easily damaged, while the steel tube is not easily damaged.

Different shrink films correspond to different products, so it is necessary to choose different types of heat shrink packaging machines according to the different characteristics of the products. When choosing, you need to comprehensively consider your actual needs to select a heat shrink packaging machine that suits you.
