In modern society, consumers demand more and more food packaging, especially food packaging. The most popular food packaging in the market is thermoforming packaging, which can reduce the floor space and extend the shelf life. For example, common beef, pork and other foods that need to be placed for a few days can be packaged by thermoforming. Not only meat needs vacuum thermoforming, but also other common pharmaceutical industries, seafood industries and hardware industries are widely used.

In the modern food packaging industry, the technological demand for automatic thermoforming food packaging machines has soared. The following are several common technological types according to different product characteristics, appearance and fresh-keeping requirements：

一: Vacuum packaging machine:

The technological principle of Vacuum packaging machine: after the lower film is formed, the product is put in, and finally the upper film is covered, and the air in the package is pumped out by a vacuum pump to form an oxygen-free environment, and finally the vacuum packaging machine is sealed by heat sealing. The main purpose is to delay oxidation and bacterial proliferation and prolong the shelf life. It is often used in dried fruits such as sausage ham and condiments.

二: Food tray sealer machine:

The technological principle of Food tray sealer machine ：After vacuumizing the air in the package, the mixed gas with a good proportion and commonly used nitrogen are filled into the package, and finally sealed. The main principle is to prevent the packaged goods from loosening or crushing, and to extend the shelf life through a certain proportion of mixed gas, which is often used in baking industry, fresh meat, sweets and cakes.

三: Thermoforming machine for food packaging

The technological principle of vacuum thermoforming process:

Mainly using high-temperature heating materials (PP, PET, PLA), combined with vacuum extraction and shaping, first, the lower film is deeply stretched and stuck on the mold to form a higher or deeper tray shape. This packaging form is mostly used to load products with relatively large thickness. Its main functional advantage is that the size can be well adapted to products with different sizes, and the sealing degree is high, which can facilitate the transportation of products that are not easy to damage. It is often used in meat products, cheese industry and other industries.

1. Product types and packaging requirements for processing

Different products are packaged in different ways. First, make sure that you want to package meat, cheese or candy, biscuits, fruits, etc. Determine the product category and size, production output, preservation degree, and facilitate the determination of the correct packaging machine type.

2：food packaging machine cost：

At the beginning, it is not only necessary to buy a machine for the first packaging machine, but also consider the cost of packaging film, labor cost, daily maintenance of equipment and accessories. In the long run, if you want to directly reduce these total costs, the higher the degree of automation, the higher the utilization rate of film, and the indirect cost savings.

3. Understand the packaging technology of various types of packaging machines:

As a novice, knowing the working principle and technology of different kinds of packaging machines is to help you judge whether the machine can meet your needs and requirements, and you also have a basic judgment. If you really don't want to waste your time understanding, then I suggest you find OrangeMech. As a manufacturer with 13 years' experience in packaging machine equipment processing, you only need to tell what your packaged products are and what the final effect you want. One-stop service will enable you to realize the "turn-key" project of packaging machine.

4. Support for after-sales totals:

Buying an automated packaging machine is a long-term equipment, and there are many problems such as technical support and equipment use training, whether accessories can be supplied in time, whether the daily maintenance of the equipment is simple, how long the warranty period is, and whether remote guidance is provided.

5. Mold replacement output expansion:

The novice's first reaction is to buy a packaging machine suitable for the present use, but if you want to use it for a long time, then you should consider whether you want to expand production and upgrade equipment in the future, especially if it is convenient to replace molds with different product types and sizes, whether there is an additional automatic printing system, and whether you can add machines to the original equipment for use if you expand and upgrade. The purpose is to reduce the cost of secondary investment.

If you are a novice and want to expand production and upgrade packaging machinery, you need to combine five precautions to choose a suitable food packaging machine: product type requirements, packaging technology, total cost, after-sales and expansibility. Knowing this information in advance will help you find a cost-effective packaging machine that suits you within your budget.
