How to choose the type of food packaging bag?

　　The bag type is an important part of food packaging. The bag type will affect the food capacity, sealing, price, etc. It does not allow materials. The selected bag type will vary with different categories. Today, the teacher of Kazuo Consulting Factory analyzed how to choose the bag type of food packaging bags.

　　1、 Cost.

　　Influenced by production process, consumption rate and other factors, under the same specification, there is a certain difference in packaging unit price of different bag types. Three side sealing bag is the most basic bag type, and the production process is relatively simple, so the unit price is also low. The three side sealing bag is suitable for most food packaging and can be used as the inner bag of food packaging. The three side sealing bag has strong expansibility and can be customized as required. The resealable zipper, easy tear opening and hanging hole for shelf display can all be realized on the three side sealing bag.

　　2、 Aesthetics.

　　The visual impact brought by the face value is very intuitive, as is the visual effect brought by the bag shape. The three side sealing bag can only be hung on the shelf or placed flat on the platform, while the self-supporting bag and the eight side sealing bag can stand on the shelf, which is much wider visually, and will bring quality bonus to the product to a certain extent. In addition, the eight side seal and four side seal have larger printing area, which can display more product information. A line of small characters at the bottom of the self-supporting bag may bring a fresh feeling to consumers. The special-shaped bag has a packaging method different from the traditional bag,

　　3、 Yield.

　　For enterprises with large production capacity, they can equip their own filling machines to roll film, which is more efficient and sanitary.

　　4、 Practicability.

　　The actual storage mode and use mode of food shall be considered for bag type. For example, frozen products are stored in the environment of minus 18, and the products and bags are relatively hard. In order to avoid mutual collision and puncture of packaging bags, back sealing bags are generally selected. For example, for liquid plastic packaging, considering the fluidity and instability of liquid, self-supporting bags are generally selected. Usually, suction nozzles are added to improve convenience. This type of bag is usually selected for sucking jelly, bagged juice, etc.
