Fresh-keeping bags are widely used in supermarkets, mainly focusing on food preservation, hygiene management and convenience. The following are specific application scenarios and functions:
1. Fresh food preservation
Fruit and vegetable area: used to pack bulk vegetables and fruits to prevent water loss and extend the shelf life.
Meat/aquatic area:
Isolate blood and water to avoid cross-contamination.
Some supermarkets provide vacuum fresh-keeping bags for high-end meat or seafood to extend the refrigeration/freezing time.
Delicious food/baking area: Pack cut cakes, stewed food, etc. to prevent oxidation and odor.
2. Bulk food packaging
Dried fruits, candies, and grains: Customers can take fresh-keeping bags to pack bulk goods, which is convenient for weighing and maintains hygiene.
Frozen fast food: such as dumplings, glutinous rice balls, etc., to prevent frost or adhesion after freezing.
3. Hygiene protection
Self-service packaging area: provide fresh-keeping bags to cover lunch boxes or directly pack take-out food (such as buns and pancakes) to avoid contamination.
Tasting session: used to pack small portions of tasting products to ensure hygiene and safety.
4. Convenience service
Temporary packaging: When customers buy leaky goods (such as tofu and live fish), they can use fresh-keeping bags for secondary reinforcement.
Emergency supplies: Some supermarkets provide small fresh-keeping bags at the checkout counter to replace shopping bags for small items.
5. Internal management of supermarkets
Ingredient pretreatment: The back kitchen packs semi-finished products for sale (such as cut clean vegetables).
Inventory management: For short-term storage of goods that need to be refrigerated, mark the date to facilitate "first in, first out".
6. Special function fresh-keeping bags
Degradable materials: Environmentally friendly supermarkets provide PLA (polylactic acid) fresh-keeping bags, which comply with the plastic restriction policy.
Microwave/freezer-specific: Clearly mark the applicable scenarios to facilitate customers to directly heat or freeze.
7. Advantages of using fresh-keeping bags in supermarkets
Reducing costs: lighter and space-saving than hard packaging.
Improving experience: transparent design makes it easy to view the contents, and zipper models enhance sealing.
Reduce loss: effectively delay food spoilage and reduce return rate.
8. Notes
Some areas charge for plastic bags, supermarkets need to provide reusable environmentally friendly options.
It is necessary to avoid mixing with non-food grade plastic bags such as PVC to ensure safety.
Fresh-keeping bags are both a necessary tool in supermarkets and a detailed design to improve customer satisfaction. Reasonable use can balance hygiene, cost and convenience.
