In modern households and businesses, food storage roll bags have become a common packaging choice. It not only prolongs the shelf life of food ingredients, but also facilitates operations such as packaging, refrigeration, freezing, and heating. However, there are many types of food roll bags on the market, with different materials, thicknesses, sizes, and functions, and consumers often have no idea where to start. So, how to choose a high-quality roll-up fresh-keeping bag that suits your needs? We will explain it in detail for you.
1. Definition and use of food fresh-keeping roll bags
Food storage roll bag is a continuous roll plastic bag that can be cut on demand. It is often used in food classification, vacuum packaging, frozen storage, microwave heating, travel and portable, take-out packaging and other scenarios. Compared with traditional bulk bags, the roll design saves more space and is more suitable for batch use.
2. Key factors for selecting food roll bags
1.1 Is the material safe and environmentally friendly?
High-quality food storage roll bags should be made of food-grade materials. Common materials include:
PA+PE composite film: suitable for vacuum packaging, with good air tightness and temperature resistance;
PE (polyethylene): soft and resistant to low temperatures, commonly used for refrigeration and freezing;
EVOH multi-layer co-extrusion film: high barrier properties, suitable for food with a long shelf life.
It is recommended to choose products that have passed FDA certification, SGS testing, and ISO standards to ensure food contact safety.
1.2 Is the thickness appropriate?
The thickness affects the bag's load-bearing capacity and tear resistance. Common thicknesses are:
60~90 microns: suitable for home refrigeration and freezing;
Above 100 microns: suitable for commercial vacuum machines and large-capacity packaging.
If it is too thin, it is easy to break, and if it is too thick, it is not easy to heat seal. When purchasing, you need to weigh it according to the usage scenario.
1.3 Bag structure design
Embossed design: Some roll bags have one smooth side and one embossed side, which can enhance the efficiency of air extraction and improve the vacuum preservation effect;
Glossy design: suitable for general preservation and freezing, not recommended for vacuum packaging;
Perforated tear line design: convenient for tearing and quick packaging.
1.4 Adaptability and compatibility
Confirm whether the roll bag you purchased is compatible with your vacuum sealer or heat sealing equipment. If it is a multi-purpose requirement, it is recommended to purchase a universal bag that can be microwaved, frozen, and refrigerated.
1.5 Whether it is easy to tear and convenient to use
Whether the roll point break line design is neat;
Whether the roll core size is suitable for household dispensers;
3. Wide range of applications to meet different needs
