Potato chips made by the potato chips plant machine belong to fried foods, which are easily oxidized and damped in air. To keep potato chips crispy in packaging is a major concern for many potato chip manufacturers. A professional potato chips packing machine is an important one among the potato chips plant machines. At present, potato chip packaging is divided into two types, that is, bagged and canned. The bagged potato chips are mostly made of aluminum-plastic composite film or aluminum-plated composite film. Canned potato chips are basically made of paper aluminum-plastic composite barrels with good sealing.
How to pack potato chips with potato chips plant machine?
To pack potato chips, it is efficient to apply a suitable potato chips plant machine to complete the demanding tasks. In order to ensure that the potato chips are not easily oxidized or crushed, the inside of the package needs to eliminate the presence of O2 in the packaging process of the potato chip processing line. Two common methods are filling the containers with nitrogen (N2), and vacuum packing. Nitrogen is a common protective gas, which does not react with other substances under normal conditions, so it is very suitable for inflatable packaging. If the packaging material has a poor barrier to N2 or the packaging is not tight, it is easy to change the content of N2 or O2 in the package. As the result, the nitrogen-filled packaging cannot protect the potato chips.
What is the common structure of the potato chip packaging bag?
Besides the potato chips plant machine, it deserves to pay attention to potato chips packing materials. The requirements of potato chip packaging bags are light protection, oxygen barrier performance, good airtightness, and packaging cost control.
The packaging material used for potato chips is called composite film packaging bag, which is composed of OPP printed film, PET aluminized barrier layer, PE heat sealing layer. The aluminum layer is not in direct contact with food, but food-grade plastics. The common potato chip packaging bag is a composite structure of OPP printed film, PET aluminized film, and PE heat seal film. The popular structures are BOPP/VMPET/PE, BOPP/VMPET/CPP, BOPP/VMPET/EX-PE/P, etc. Apart from packing material structure, the appearance design of potato chips packages is also changing. Some potato chip packaging is very creative, and the unique bag shape can well differentiate the brand.
The consumption of potato chips is increasing
Potato chips are hot sales with high demand and high turnover rate. Commercial potato chips plant machines is an efficient solution for mass production of potato chips. The development of foreign potato chip packaging bags is still pursuing thinning, simplification, and sustainability of composite structures while ensuring packaging performance. The latest packaging structure is a composite of 18 microns OPP printed heat seal film and 18 micron OPP aluminum heat seal film. In addition to saving material, it can also save costs and facilitate recycling and regeneration.
In recent years, there have been more and more people eating potato chips. The national potato chip purchase penetration rate has reached 76% overall. The domestic potato chip market has developed rapidly and the market size has continued to expand.
The potato chips market is highly competitive
At the same time, the competition for potato chips is fierce. Well-known brands such as Leshi, Pringles, Cubeco, Abili, and Holiyou continue to launch new tastes in order to attract more customers. In addition, retail prices are also highly competitive. These brands not only have advanced potato chips plant machines but also carry out wise marketing strategies.
