Biscuit packaging box production process requirements

1. The structural characteristics of biscuits and their technical requirements for packaging

Biscuit is a convenient food that people like to eat. It uses flour, oil, sucrose, etc. as the main raw materials, and dairy products, eggs, loosening agents, flavoring agents, etc. as auxiliary raw materials, processed through processes such as kneading, molding, and baking. The biscuits are baked, and the moisture content is mostly below 10%, generally 4-6%. After they are pressurized and heated, the volume of the raw material itself is expanded, and the internal structure of the material is also changed. After processing and molding, they are made. Due to the porous and fluffy tissue structure of this kind of food, the taste is crisp and sweet, and has certain nutritional value. Once moisture is absorbed and the water content increases, the biscuits will soften and the quality will be greatly reduced. Therefore, the most important thing in the packaging of biscuits is moisture-proof packaging. Secondly, some biscuits contain a lot of fat, and the fat is easy to oxidize when exposed to light. This is also the packaging. Should be considered. Therefore, light-shielding sealed packaging should be mainly used in biscuit packaging, and on this basis, its commercial nature should be considered. There are several common ways to pack biscuits:

(1) Sealed packaging with plastic film;

(2) Wrapped in wax paper;

(3) Carton packaging;

(4) Metal packaging box.

2. Design of protective function of biscuit packaging

1） Moisture-proof and mildew-proof, barrier, film smoothness, ink standard regulations

Biscuits are puffed small foods, and their packaging uses composite film bags. According to the technical requirements of food packaging, it should be processed in accordance with the international standards for moisture-proof (GB5048), mildew-proof (GB4768), barrier properties (GB1974-2005), film smoothness (GB10006), and ink properties (GB7707) packaging regulations. Moisture-proof treatment is generally achieved by PET/VMAL/CPP composite film bags and placing an appropriate amount of desiccant in the package to meet the protection requirements. Anti-mold performance should be tested in accordance with the anti-mold packaging test method: After testing in accordance with the provisions of (GB4768), the appearance quality and related performance of the food should meet the requirements of the product standard, and no mold will grow during the validity period.

2） Shockproof packaging

Biscuits are a fragile product. In the process of product circulation, corrugated cartons are generally used. Corrugated cartons have good cushioning performance and compression resistance. The materials and structure of the cartons can also be improved according to different needs, and the cost is low. Therefore, In the transportation and packaging of biscuits, corrugated boxes play a leading role. According to relevant regulations and calculations, 0402-shaped corrugated boxes are selected for puffed small food packaging boxes

3） Light-proof packaging

Generally speaking, packaging with transparent film is not recommended.

4） The protective performance test of the package

In order to check the degree of protection of the biscuit packaging, the packages are subjected to tests such as stacking, vibration, pressure resistance, and drop. The stacking test is to evaluate the compressive strength of the puffed food packages when they are stacked and the protective function of the packaging box for puffed small foods. The vibration test is replaced by a simulated vehicle transportation vibration test. The vibration test is performed on a simulated vehicle vibration table for 7 seconds, which is equivalent to transporting a refrigerator package of 200KM on a tertiary road to test the protection ability of the packaging on the product.
