What is overwrapping machine?

When it comes to transparent film packaging machines, you must be familiar with them, also known as three-dimensional overwrapping machines and three-dimensional transparent film overwrapping machines. For packaging equipment, it belongs to the category of equipment accessories. The packaging speed of this machine is fast, the operation is stable, and the variety is changed quickly. Fully automatic packaging, with frequency conversion speed regulation, fault alarm, machine jog adjustment, and counting functions. The packaged product is flat and beautiful, improves the product grade, has firm sealing, good sealing, anti-counterfeiting, moisture-proof, and easy to unpack.

Usually, the packaging film is cut into a length that meets the packaging requirements by a cutter, the small packaging box is conveyed by a conveyor, the cylinder pushes the stacking (according to the required form and quantity), and the film is wrapped and folded to form a medium-sized package. Since this equipment does not have a heat-shrinkable packaging machine, the heat-sealing oven will heat the packaged object as a whole, and the use of local point and instant low-temperature packaging will not cause temperature changes in the packaging in the box, which is relatively called a cold-packing machine. An alternative to heat shrink wrapping machines.

The usage of overwrapping machine

It has a wide range of applications, and is widely used in the three-dimensional automatic wrapping of a single piece of transparent film for various box-shaped items in the industries of stationery, health care products, food, medicine, and cosmetics. At this stage, there are many highly automated packaging machinery in the packaging industry, but they can be summarized into two categories. One is a three-dimensional overwrapping machine, and the other is a shrink wrapping machine.

The difference of overwrapping machine and shrink wrapping machine

The packaging method of the three-dimensional overwrapping machine is to wrap the film on the outside of the product, and then extract the air from the internal equipment to form a vacuum environment, so that the film can stick to the outside of the product. Therefore, the three-dimensional overwrapping machine will also be called a film packaging machine.

The packaging film used by the shrink overwrapping machine is actually a film, but the reason why its name is not a film packaging machine is the way it is packaged. The principle of shrink overwrapping machine is very different from that of three-dimensional overwrapping machine. The packaging material is also a film, but the inside of the shrink overwrapping machine uses the principle of heat energy to shrink the film to heat the inside, so that the film shrinks tightly to the outside of the product. So shrink wrapping machine is also called heat shrink wrapping machine. The three-dimensional overwrapping machine is more energy-saving and power-saving than the heat-shrinkable packaging machine, and is fully sealed, waterproof, moisture-proof, and infection-proof, and can even replace the heat-shrinkable packaging machine in some fields.

How to select packaging machine?

1. First of all, you must determine which products you want to pack in the packaging machine you will buy. Packaging machinery manufacturers generally have a lot of product varieties, but some of them want to be able to package all types of products through one device when purchasing packaging equipment. In fact, this is a very wrong idea, because generally speaking, special machine Better than the packaging of a compatible machine. The varieties that can be packaged by one packaging equipment should not exceed 5 varieties as far as possible, and the products with too large size gap should be packaged separately.

2. High cost performance. At present, the quality of domestic packaging machines has been greatly improved, so the quality of domestic machines is comparable to imported machines, and the price of domestic machines is much lower than that of imported machines.

3. As far as possible, choose a machine with simple operation and maintenance, complete accessories and automatic continuous feeding, which can improve the packaging efficiency and reduce labor costs, which is suitable for the long-term development of the enterprise.

4. Choose a packaging machine company with a long history as much as possible, and the quality is guaranteed. Choosing a machine produced by an enterprise with mature technology and stable quality can basically achieve the effect of faster and more stable machine, low energy consumption, low manual work and low scrap rate. In the process of use, if you buy low-quality machines, the amount of packaging film that will be wasted in daily production in the future will not be a small amount, especially now that the packaging materials are rising.
