Vacuum packaging is a common packaging method in modern society. It can extend the shelf life of food, prevent food from deteriorating, and also has a certain aroma retention effect. In vacuum packaging, the common classifications are textured packaging and smooth packaging. So what is the difference between these two types of packaging? In what fields are they suitable for application? We together look.
Differences in appearance and texture:
Smooth vacuum packaging bags mean that the entire surface of the bag is very smooth, with no obvious lines or unevenness. Smooth vacuum packaging bags are usually made of high-strength materials and have good oxygen isolation and antibacterial properties, which can effectively protect the freshness and taste of food. In addition, glossy vacuum packaging bags are easy to clean and can be used repeatedly.
Textured vacuum packaging bags refer to bags with obvious textures or lines on the surface, and sometimes they may feel uneven. Textured vacuum packaging bags are usually made of low-strength materials and are easy to fold and store.
Functional differences:
Glossy vacuum bags are easier to seal and vacuum due to their smooth surface, and are more convenient to operate. In addition, due to its high transparency, it is easier to observe the storage status of food. Due to its special structural design, textured vacuum bags can better protect the shape and integrity of food, and are especially suitable for preserving some foods that need to remain intact, such as local products, dried fruits, etc.
Material difference:
Textured and smooth vacuum bags are made of different materials. Textured vacuum bags are mainly made of polyethylene (PE), while smooth vacuum bags are made of nylon (PA) and polyethylene (PE) as the main raw materials. Compared with textured vacuum bags, glossy vacuum bags are made of tougher materials and have stronger carrying capacity. For example, vacuum preservation bags suitable for outdoor sports such as camping and traveling are generally made of glossy materials.
Safety and environmental performance:
In terms of safety, both smooth vacuum bags and textured vacuum bags have undergone strict testing and certification and comply with relevant national standards. However, due to the texture on the surface of the textured vacuum bag, tiny cracks may occur during the vacuuming process, thus affecting food safety. Therefore, when choosing textured vacuum bags, choose products with reliable quality. Both bags are certified biodegradable in terms of environmental protection, but the textured vacuum bag is more difficult to recycle due to its special structure.
Application differences:
The surface of the textured vacuum bag has obvious mesh textures, which can effectively prevent food from being squeezed and deformed during transportation. Suitable for storing fragile or easily deformed foods, such as fish, vegetables, etc. It is also suitable for food packaging that does not require high ventilation, such as dried meat, dried tofu, etc.; while glossy vacuum bags have a smooth surface and no obvious lines, so they are suitable for food packaging that requires moisture-proof, waterproof, and strong load-bearing capacity, such as water-resistant bags. Products, meats, nuts, candies, etc.
In short, when consumers purchase vacuum bags, they can choose vacuum bags of different materials, textures, and thicknesses based on the characteristics of the food and packaging needs.
