Shrink Wrap In Operation Cost

Perhaps you did not find that packaging has an important position in the production process and constitutes the latest stage of production. It is often overlooked that there are serious losses in this process. Although you have serious knowledge and experience in the production of products, you do not give the necessary attention to packaging. More unfortunately, you are not sensitive for the calculation of labor-related and quality-related losses in packaging.

From textiles to stationery, from food to automobiles, there are broad prospects of shrink packaging. Unipolar shrinking machines have always provided temporary solutions for small and medium enterprises. However, there is still a certain difference between such a machine and the industrial solution. This is also the general consensus of the entire industrial packaging industry.

Introducing a packaging machine that meets your needs is an important measure to solve the above problems. From the perspective of a company’s input and cost calculation, the shrinking machine is a long-term investment project, and the membrane is a commercial expenditure. What you and we are reluctant to see is the failure of double investment on low-quality packaging machines and films. In order to avoid this problem, as a shrink machine that is bought only once, it should be taken care to maximize the potential of the film.

Importance of Shrink Packaging

Nowadays, shrink packaging has become a more mature product in foreign trade. The application of the servo system widely appears in people’s daily life. The development of science and technology has enabled software and hardware to breed sophisticated and complex products in order to adapt and increase people’s growing consumer demand and life needs.It has long been mechatronics, and the transformation of mechanical design concepts and program applications can be realized at an extremely fast speed. The shrink packaging machine is not only the machine design itself but also the actual application. These are the situations that the shrink machine designer must think of and solve. It can be said that the project design department is the most important and tense department in the entire shrink machine work process.

FHOPE is not only an excellent manufacturer of wrapping machines, but also provides good shrinking machine to help customers. The key to production efficiency is the speed of product packaging and how many products need shrink packaging. This answer is reflected in the productivity of the workshop and the production costs of the department. Although the industrial scale and production infrastructure have been gradually developed, and the profit margin of products has declined, manufacturers have adopted strict production facility control measures to reduce production costs and recalculate production efficiency. This is where the packaging efficiency is outstanding.

Choosing the Right Shrink Film and Shrink Machine

Right shrink film

 

Only the correct film can perform the function of the shrinking machine. The right shrinking film means the right specifications and the proper quality. The film size is determined by the size of the product. A film that is too small cannot wrap around the product. A film that is too large can easily cause film wasting and get bad shrinking performance. The quality of the shrink film takes a obvious role in the first stage of film bagging and the second stage of heating. A good film is not sticky to the cutter and is easy cut off. Bad quality film is easy to destroy the shrinkage effect. Right shrink film can reduce the precision requirement of the sealing machine performance and heating tunnel.

Right shrink machine

At same time, right shrink machine has the ability of reducing the other workloads. Right shrink machine means high qualified sealing machine and heating tunnel. But this is only theoretically conjectured and there are certain difficulties and risks in actual operation. Especially by purchasing high prices film to make up for the lack of machinery and equipment, the total contraction cost will be increased by increasing the film cost without using the machine cost.

L-welding and Continuous Sealer for Shrink Packaging Machines

 

  1. L-welding shrink machine

For the first time shrinking of a new film roll, it needs to close one side by manual machine operation for cutting the side. Secondly, the two sides are to be closed by a special moving cutting device. With the assistance of the L-shaped cutter, the product is closed fully around. For the second shrinking, a side is closed by the first shrinking process, other two sides are held tightly by the jaw and the process is repeated in cycle automatically. The machine goes well with the film bagging and shrinking.

2. Continuous Sealer Shrink Machine

Same as the L-bar shrinking machine, three sides of the film are to be closed, and a side is folded itself. The film cutter is continuous for sealing by a sewing machine roll from the upstream. That is to say that the film passes through the sewing roll like water flow, so that sealing is infinitely to make sure in the length of the product. The left side is to seal by a vertical moving cutter with one-way welding. The products are transported on the belt when shaking or acceleration, the continuous sealer machine won’t be the hard stop and has separate speed.

Brief Introduction of Shrink Machine

Generally, goods packaging with shrink wrap is designed to the product with heating method. Shrinking machine usually has been performed with varieties of standards. For an instance, shrink film enters the packaging machine in the form of a film roll so that the machine has a special device for the shrinking film roll. The two layers of shrinking film are open on the framer with a center folded mark. Based on this film former design, the product to be packaged is conveyed matching with the speed of the film feeding-in from a side, and then entered into the folding center of the film. The film completes wrapping surrounding the product and is still placed on the folded line, other three sides film are coming with the welding process.

Commonly speaking, the shrinking machine has two types based on the film folded and welding way. One side of the film is folded by itself, other three sides are open. According to the different treatment of the film cutting, different machines are come out and corresponding different applications are produced.

Shrinking machine : how to choose right the film and machine (B)

www.fhopepack.com for automatic side seal shrinking machine

In the previous post, L-Bar shrinking machine was introduced. This time we continue to talk about how to choose the correct shrinking machine. Side seal shrinking machine has unparalleled advantages of the L-Bar shrinking machine, which is called the most advanced shrinking machine.

Side seal shrinking machine,

The same as the forming mechanism of the L-Bar telescopic machine, one side of the film is folded by the forming machine and the other three sides are open, which needs to pass through the cutting knife to form a closed bag. The cutting knife structure of the sealing machine is unique. The vertical blades of the upper and lower movable parts are fixed on the machine and are not movable parts. The film is carried out by rollers. The length of the product is not limited. Continuous cutting is completed by the horizontal knife.

The continuous operation of the cutter system closely cooperates with the speed of the product conveyor line, and the continuous cutter movement is completed during continuous transportation, which increases the degree of automation.

Therefore, the limit of the length of the product that the side sealing machine does not convey has more practical mechanical significance and value. In addition to selecting the correct shrink machine, it is also necessary to pay attention to the correct shrink film. There are two main points: an appropriate film size, and the quality of the film. Both through continuous cutting, and adaptation to the shrink tunnel

The correct machine and the correct film selection can exert the maximum energy and utilization rate of the shrinking machine.

Shrinking machine : how to choose right the film and machine (A)

For machine users, choosing right shrinking material and right machine, is the most important.

After all, the purchase of machinery is not a small expense. The packaging machine is self-evident for the final circulation of the entire product and the value obtained. The correct machine can bring good long-term profits and company image. Bringing in incorrect shrinking machine, is inconvenient for operation and poor user experience, even sometimes it is not possible to use products that are not equipped with oneself, resulting in a waste of resources and an increase in operating costs.

 

We can use an experiment to illustrate the use of two different shrinking methods.

One method, L-Bar shrinking

Another method, Side sealing

L-Bar shrinking machine,

Before automatic running, it needs to close one side film manual to form a sewing, while adjacent side folded by the film frame. The other two sides will be cutting by L-Bar mechanical structure to close the film for a full bag. One bag finishes, next product has a sewing side naturally, and L-shaped cutter resume automatically waiting for next welding. This process is constant circulation. This is the working principle and action principle of L-Bar jaw.
