Manual and industrial bag sealer. Main types of equipment
Packer, the price of which today is from 5000 rubles. for manual models and from 20 000 rubles. for industrial units, available to a wide range of consumers. The equipment finds its application both in the implementation of everyday tasks and in production. Such devices make it easier to pack products in plastic wrap and put the process on stream.
Using a manual bag sealer, just like industrial models, is quite simple. For a start, the device is configured to work with a material of a certain thickness. Next, the polyethylene is laid on the working plane, the clamping lever is activated, and after a few seconds, ready-made sealed packaging is available.
It is convenient to stack any products made with the help of special equipment, which takes on a neat, attractive look.
Types of stitches
Despite the fact that the manual bag sealer is somewhat different from the desktop and floor units, the operation of such equipment is aimed at the implementation of the same tasks, namely to obtain a strong and neat weld.
Despite the diversity of the range of modern zapayschikov, differ only a few types of seams. Thus, the cutting connection is obtained by treating the material with a heating element of circular cross section. Most often for reliable sealing, hot nichrome wire is used here, to which particles of polyethylene do not stick.
The flat seam practically does not differ from the previous one in appearance. The only difference is the possibility of creating a wider connection due to the use of heating heating elements as an alternative to the nichrome strips.
Any modern bag sealer, manual or industrial, is suitable for working with materials such as:
- Vacuum and multilayer film.
- Metallized film.
Main types of zapayshchik
A number of efficient polyethylene sealers are available for domestic consumers.Different modifications differ in performance, individual parameters of seams, power, ease of use, method of connecting surfaces.
Among the common options worth noting the following zapayschiki:
- Hand held
- Conveyor belt
- Continuous heating devices.
Let's look at the most popular devices for working with the above materials.
Manual bag sealer is a budget, but at the same time reliable device. The equipment of this category is convenient to use both in the household and in small production where mass production of packaging is not required.
The scope of application of such devices are limited only by the imagination of users. The manual bag sealer with a knife is successfully used to seal the bags in the production of semi-finished products, packing of offal, and sorting food at points of sale.
Impulse sealing machine
Differ in simplicity of a design, rather low price, profitability. At the same time, there are some restrictions on the use of such devices.In the first place there is the lack of opportunities for long-term, continuous operation, the creation of seams of a certain length and thickness. Among other things, such devices work with a limited range of materials.
There are several types of pulse devices:
- The zapayshchik of packages desktop - possesses the heating tire up to 80 cm wide. The budgetary models widespread in life differ in existence of the plastic case. For production use, it is recommended to purchase a more reliable zapayschik package desktop with a metal case.
- Floor sealing machine - contains a platform for creating seams with a width of about 100 cm. Devices in this category contain functional elements for automatic cutting of material and are supplied with additional tires.
Zapayshchiki constant heating
Characterized by the possibility of long-term, intensive operation, the presence of individual modes of operation. Equally effective when sealing thin, thick and multi-layered materials.
Most models are suitable for mass production of packaging with the creation of imprints of the date of manufacture on the seams in automatic mode. Thin adjustment of the temperature of the connecting bus allows reliable and accurate sealing.
As for the drawbacks of such units, impressive weight and dimensions come out on top. The standard roller sealing machine of constant heating packages allows making seams up to 40 cm wide, which can also be considered a minus in the case of serial packaging production.
Conveyor sealing machine
Conveyor-type devices are the most versatile among all units of this mission. Suitable for efficient sealing of polymer films, ready-made packages, multilayer bases.
Most models have the function of melting materials using heating elements, hot air, ultrasound and infrared radiation.
Among the main advantages of conveyor-type units, it is worth noting:
- Ability to work with a wide range of materials.
- Automatic operation.
- High level of performance.
- No restrictions on the width of sealing.
- Creating high-quality seams.
The disadvantages include a limited number of available configurations and design solutions, high cost. At the same time, as practice shows, conveyor equipment pays off within a few months.
