Recently, in order to help readers better understand the professional terms in the field of plastic and aluminum foil packaging bags, a list of common abbreviations and symbols has been compiled.
Key Abbreviations in Plastic Packagingï¼
- HDPE (High-Density Polyethylene): This high-strength material is ideal for heavy-duty packaging products, commonly used in industrial applications.
- LDPE (Low-Density Polyethylene): Known for its softness and transparency, LDPE is frequently used in cling films and lightweight packaging.
- LLDPE (Linear Low-Density Polyethylene): With outstanding tensile and tear resistance, LLDPE is widely applied in stretch films and agricultural covers.
- MDPE (Medium-Density Polyethylene): Offers a balance between flexibility and strength, suitable for gas pipes and packaging.
- PP (Polypropylene): This versatile polymer includes BOPP, often utilized in food packaging for its transparency and barrier properties, and CPP for its flexibility and heat-sealing abilities.
- PET (Polyethylene Terephthalate): BOPET is a popular form of PET used for high-end, durable packaging solutions.
- PA (Polyamide): BOPA, known for its excellent barrier properties, is widely used in food and pharmaceutical packaging.
Aluminum Foil Abbreviations:
- AL (Aluminum Foil): Recognized for its excellent barrier properties, aluminum foil is essential in preserving food freshness and preventing contamination.
- VM-BOPP: Vacuum metalized biaxially oriented polypropylene, used for a shiny, metallic finish in packaging.
- VM-BOPET: Vacuum metalized biaxially oriented PET, commonly applied for enhanced barrier properties in packaging films.
Important Symbols in Packaging Processes:
- /dr. (Dry Compounding): A method involving the drying of adhesives before layering materials.
- /sf. (Solvent-Free Compounding): Utilizes 100% solid adhesives for environmentally friendly packaging solutions.
- /wt. (Wet Compounding): A direct compounding method without pre-drying, suitable for certain packaging applications.
- /ex. (Extrusion Compounding): This process involves melting plastics and applying them to substrates to create composite films.
- /co. (Co-Extrusion Compounding): Combines multiple layers in one process for creating multi-functional packaging materials.
Understanding these industry-specific abbreviations and symbols is crucial for selecting the right materials, ensuring both the quality and sustainability of packaging solutions.
