Puffed food packaging bag

Puffed food packaging bag is a type of packaging material specially used to encapsulate puffed food, aiming to protect the quality of the food, prolong the shelf life and enhance the attractiveness of the product. Puffed food, mainly from grains, potatoes, beans and other raw materials through the puffing process, which is characterised by volume expansion, crispy taste. These foods have special requirements for packaging because of their brittle texture and susceptibility to moisture absorption and deterioration.

Features

1. Moisture and oxygen resistance: puffed food is susceptible to moisture and softening, and the oil is easy to oxidise, so the bags are usually made of multi-layer composite materials, the inner layer is often filled with nitrogen or other inert gases to isolate the oxygen and moisture, to maintain the crunchy texture of the food and extend the shelf life.
2. Pressure resistance and breakage: Because puffed food is fragile, the bags need to have enough mechanical strength and toughness to prevent breakage during transport and sales.
3. Transparent or high barrier: According to the product demand, the packaging can be designed as transparent to show the colour of food, or using high barrier materials, effectively blocking light, smell and other external factors, to protect the original taste of food.
4. Sealing: good sealing technology to ensure the sealing of the package to prevent air leakage and contamination, and at the same time easy for consumers to open.
5. Printing and design: The printing patterns on the bags are bright and attractive, often combined with brand elements and product characteristics to enhance market competitiveness.

Applications

1. Protecting food quality: By isolating air, moisture and light, it effectively prevents the growth of microorganisms and chemical reactions, ensuring the freshness and safety of food.
2. Enhance the value of goods: Well-designed packaging not only protects the food, but also improves the visual appeal of the product, promotes sales and increases brand recognition.
3. Convenient for transport and storage: Strong packaging materials and reasonable packaging design can facilitate stacking, handling and long-distance transport of commodities, and reduce losses in the logistics process.
4. environmental protection and sustainability: with the enhancement of environmental awareness, modern puffed food packaging bags are also in the development of recyclable, biodegradable materials to reduce the burden on the environment.
5. Diversified market demand to meet: different types of puffed food, such as crisps, cornflakes, shrimp crackers, etc., its bag design will be adjusted according to the characteristics of different products to meet the needs of different consumer scenarios and crowds.
