Generally speaking, special-shaped bags also belong to the level of plastic flexible packaging, and are available for all flexible packaging materials and structural foundations. Therefore, the most basic design principles are still the same as general flexible packaging bags. In addition, when designing, we must first consider relevant laws and regulations, the role of packaging bags and its quality commitment system software. Laws and regulations refer to the laws and regulations, policies and regulations formulated by the state for related commodities; the role regulations include various isolation characteristics, storage characteristics, and machine characteristics; the quality commitment system software means that the availability of production must be taken into account. Reliability and so on. With this kind of foundation in mind, you can select the appropriate packaging supplies and basic plan design for the product.
In addition to the most basic factors mentioned above, the following contents must generally be paid attention to when designing special-shaped bags.
1. Changes in content
After the general packaging bag is changed into a special-shaped bag, its volume will definitely change to a certain extent. Therefore, the specifications of the packaging bag must be designed again.
2. Changes in the design edge of the packaging bag
Because it is a flexible packaging bag, the outer edge of the packaging bag is not suitable for oblique angles to prevent other packaging from being pierced when it is stacked, or to damage the user.
3. The influence of encapsulation method
If the special-shaped bag is sealed with fully automatic sealing machinery and equipment, in order to facilitate the smooth development of production, there are often certain regulations for the opening position and sealing position of the special-shaped bag, which must be considered.
After fully considering the above factors, and then cooperated with each other with beautiful and generous design patterns, a successful special-shaped flexible packaging bag came out.
According to different methods, special-shaped bags can be divided into the following categories.
Special-shaped stand-up pouch with mouth
The effect of adding the mouth is to facilitate the tilting of the contents, and the goods after the mouth can be sealed again, which means that it can be unsealed several times. This kind of special-shaped bag is suitable for liquid beverages, shower gel, shampoo, ketchup, vegetable oil and other liquids, or other liquid products that must be unsealed several times.
2. Special-shaped stand-up pouch with zipper
The effect of adding a zipper is to facilitate several unsealing applications. But the difference is that the method of repeated sealing is a zipper, so this design is not suitable for encapsulating liquids, but only used for some light and dry items, such as: lollipops, nuts, chocolate, cookies, crystal jelly, tea leaves, etc. .
3. Mouth-like shaped stand-up pouch
The characteristic of this packaging bag is that there is no additional mouth in the product packaging design, but the special-shaped bag manufacturing characteristics are used to make a mouth-like bag, which is convenient to take. This design is suitable for liquid refills. Since it cannot be resealed once it is opened, the available products are basically the same as those available in the special-shaped stand-up pouch with spout.
