In the modern food industry, packaging is not only a key link to protect food from external contamination, but also an important means to ensure food freshness, extend shelf life and enhance brand image. Among them, 220L aseptic bags (Aseptic Bags) have a unique advantage and occupy a pivotal position in the food, beverage, jam, wine and other industries.
220L aseptic bags are usually made of multi-layer composite materials, including but not limited to polyethylene (PE), aluminized polyester (VMPET), etc. Taking the PE/VMPET/PE multi-layer structure as an example, this design not only gives the aseptic bag good light-proof performance, but also significantly reduces the oxygen permeability, effectively preventing food from deteriorating due to oxidation. At the same time, the multi-layer structure also enhances the heat sealing strength and air tightness of the bag, enabling it to withstand higher internal pressure and prevent breakage and leakage.
The manufacturing process of aseptic bags strictly follows the aseptic operation specifications. From raw material film blowing, cutting, heat sealing to packaging and sterilization, each step is carried out in a clean environment to ensure the sterility of the bag. This high-precision packaging technology allows food to maintain a long shelf life and original nutrients and flavor without adding preservatives or refrigeration.
Characteristics and advantages of 220L aseptic bags
High barrier properties: The use of multi-layer composite materials makes aseptic bags have barrier properties, which can effectively prevent the invasion of external factors such as oxygen, moisture, and microorganisms, thereby extending the shelf life of food.
Folding and pressure resistance: Aseptic bags are made of high-strength materials with good folding and pressure resistance. Even if they encounter bumps or squeezing during transportation and storage, they can maintain the integrity and sealing of the bags.
Environmental protection and energy saving: Compared with traditional cans or bottles, aseptic bags have smaller volume and lighter weight, reducing energy consumption and carbon emissions during transportation. At the same time, aseptic bags can also be recycled, which is in line with the concept of environmental protection.
Easy to operate: Aseptic bags are usually equipped with valves or straws, which makes it convenient and quick to pour or suck food, improving the consumer experience.
220L aseptic bags are widely used in food, beverage, jam, wine and other industries. In the food field, it can be used to package liquid or semi-fluid foods such as mineral water, juice, dairy products, cooking oil, ketchup, etc.; in the beverage industry, it is suitable for the packaging of beverages such as cola and wine.
As consumers' awareness of food safety and health continues to increase, the requirements for food packaging are becoming increasingly stringent. 220L aseptic bags meet the market's demand for high-quality packaging with their performance and environmental protection characteristics. It can not only extend the shelf life of food, maintain the freshness and flavor of food, but also reduce energy consumption and carbon emissions in the packaging process, which is in line with the concept of sustainable development.
The customized service of aseptic bags also provides more choices for food companies. Companies can customize aseptic bags of different colors, shapes and sizes according to their product characteristics and brand image, thereby enhancing the market competitiveness of their products.
