Product Details
The following factors need to be taken into consideration when selecting materials for stand-up pouches:
1.Contents properties:
-Chemical properties: whether the contents are corrosive, oxidising or other special chemical properties, which require the selection of appropriate barrier materials.
- Physical state: whether the contents are solid, liquid or powder, different states may require different strength materials.
2. Barrier properties:
- Oxygen barrier: whether it is necessary to prevent the entry of oxygen to maintain the quality of the contents.
- Moisture barrier: whether it is necessary to prevent moisture penetration to keep the contents dry.
- Light-blocking property: whether it is necessary to prevent ultraviolet rays or other light from affecting the contents.
3. physical properties:
- Strength: stand-up pouches need to be strong enough to support the weight of the contents and prevent breakage during transport and stacking.
- Flexibility: The material should be flexible so that the stand-up pouches can remain standing.
4. safety:
- FOOD GRADE: If the contents are food, the material must meet safety standards for food contact.
- Pharmaceutical grade: For pharmaceutical packaging, the material needs to comply with relevant pharmaceutical packaging regulations.
5. environmental factors:
- Recyclability: whether the material is recyclable to minimise environmental impact.
- Biodegradability: Whether biodegradable materials need to be used to reduce environmental pollution.
6. cost:
- Material cost: selecting suitable materials according to the budget, taking into account both production cost and transport cost.
- Production efficiency: certain materials may be more suitable for high-speed automated production, thus reducing long-term costs.
