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.
