Politan Gosia Zipper Storage Bags Gosia 1.5L 20 pcs (18cm x 21cm) are resealable food storage bags designed to keep food and small items protected from moisture, odors and contamination. Each bag in the 20-piece pack has a 1.5 litre capacity and measures 18 × 21 cm, with a reusable zipper closure that allows repeated opening and secure resealing for storage, freezing or transporting portions, snacks and ingredients.
Advantages
The bags offer a simple, space-efficient solution for portioning, preserving and organising food and small items. The reusable zipper closure provides quick access while maintaining a reasonably airtight seal to reduce exposure to moisture and odours. The standardized size fits easily into fridge drawers, lunch boxes and small freezer compartments, and the lightweight flexible material makes the bags easy to fold and store when not in use.
Suitable for
- Storing snacks, sandwiches and packed lunches
- Portioning ingredients such as chopped fruit, vegetables, nuts or cheese
- Freezing small portions of food for later use
- Organising toiletries, cables, small tools and travel items
- Separating components in meal prep or baking
When it may not be suitable
These bags are intended for dry or moist food items and small objects; they are not designed for long-term vacuum sealing or sous-vide cooking. They may not provide a complete barrier against strong-smelling foods over extended storage times and are not a substitute for rigid, airtight containers for fragile goods.
Key specifications
- Capacity: approximately 1.5 litres per bag
- Dimensions: 18 cm × 21 cm (width × height)
- Quantity: 20 bags per pack

How to use
Place the food or items inside the bag without overfilling to allow the zipper to close fully. Align the two sides of the zipper track and press along the length to seal; visually check that the seal is continuous to reduce air ingress. For freezing, leave a little headspace to allow expansion of liquids. After use, wash by hand if the material and local guidelines permit; inspect the zipper and film for damage and replace the bag if the seal or material is compromised.
What to consider before purchase

Usage recommendations
For best results, use these Politan Gosia zipper bags for short- to medium-term food storage, portion control and organising small items. Avoid exposing the bags to direct heat sources and replace any bag that shows tears, punctures or a weakened seal.
