Structural Design of Rice Brick Vacuum Packaging Bag
Rice brick vacuum packaging bag is a packaging solution designed specifically for rice and other grain products, with multiple functions such as preservation, insect prevention, and moisture resistance. Rice brick vacuum packaging bags are usually made of high-strength and puncture resistant plastic film materials, such as nylon (PA), polyethylene (PE), etc. These materials have good sealing and barrier properties, which can effectively prevent the invasion of oxygen, moisture, and microorganisms, thereby extending the shelf life of food.
The structural design of rice brick vacuum packaging bags is the key to their functional implementation. The following are some key points about the structural design of rice brick vacuum packaging bags:
1、 Material selection
Main materials: The main material for rice brick vacuum packaging bags is usually plastic film, such as nylon (PA), polyethylene (PE), etc. These materials have good barrier properties, puncture resistance, and sealing properties, which can effectively prevent the invasion of oxygen, moisture, and microorganisms.
Auxiliary materials: As needed, some auxiliary materials can also be added to the packaging bag, such as anti oxidants, anti UV agents, etc., to improve the freshness and durability of the packaging bag.
2、 Structural Design
Bag design: The bag shape of rice brick vacuum packaging bags is usually customized according to actual needs, and common bag shapes include rectangular, square, etc. The design of the bag should take into account the shape, volume, and weight of food products such as rice to ensure that the packaging bag can tightly fit the product and reduce air residue inside the packaging.
Sealing design: Sealing is a key part of rice brick vacuum packaging bags, usually sealed by heat sealing or high-frequency sealing methods. The design of the seal should ensure a secure seal, prevent air leakage, and facilitate consumers to open and reseal (if possible).
Handle design: In order to facilitate consumers' carrying and transportation, some rice brick vacuum packaging bags will also be equipped with handle design. The design of the handle should take into account ergonomics and load-bearing capacity to ensure that consumers can easily carry the packaging bag.
Exhaust hole design: Setting exhaust holes on the packaging bag can easily extract the air inside the bag, creating a low oxygen environment and extending the shelf life of food. The design of the exhaust hole should ensure that the gas can be smoothly discharged while avoiding the packaging bag from breaking during the vacuum pumping process.
3、 Function implementation
Preservation function: Through vacuum packaging, the oxygen inside the packaging bag is extracted to create a low oxygen environment, effectively inhibiting the growth and reproduction of microorganisms, thereby extending the shelf life of food.
Insect proof function: Vacuum packaging can prevent the invasion of insects and other pests, and protect the integrity of food products such as rice.
Moisture proof function: The packaging bag material has good barrier properties, which can effectively prevent moisture from entering and keep the food dry.
Transparency: Some rice brick vacuum packaging bags are made of transparent materials, making it convenient for consumers to observe the quality and condition of rice and other grain products inside the packaging.
4、 Precautions
Material safety: Ensure that packaging bag materials comply with food safety standards and are odorless.
Sealing test: During the production process, packaging bags should undergo sealing testing to ensure that their sealing performance meets the requirements.
Size selection: Choose the appropriate packaging bag size according to actual needs to ensure that the packaging bag can tightly fit the product and reduce air residue.
Storage conditions: During storage and use, attention should be paid to avoiding the packaging bag from being affected by adverse factors such as direct sunlight, high temperature, and humidity.
In summary, the structural design of rice brick vacuum packaging bags should comprehensively consider multiple aspects such as material selection, bag type design, sealing design, handle design, and functional implementation to ensure that they have good preservation, insect prevention, moisture resistance, and transparency functions. Meanwhile, attention should also be paid to details such as material safety, sealing testing, and size selection during the design and production process.
