3. Comprehensive, Deep-Level Applications in the Busan Market

3.1 Пакување на храна: From Bulk Export to High-End Retail

• Seafood & Frozen Food Packaging: Busan is a distribution center for premium seafood like tuna and king crab. Using 8011 foil as the middle barrier layer in stand-up pouches or vacuum bags​ effectively prevents freezer burn (surface drying from sublimation), locking in freshness and moisture to meet the quality demands of high-end markets in Japan, Европа, and America.
• Ready-to-Eat & Retort Packaging: Used in retort pouches​ for curry, soup, rice, итн. Laminated with heat-resistant materials like CPP, it withstands sterilization above 121°C, enabling convenient microwave or boil-in-bag preparation and greatly expanding the global market for Korean instant foods.
• Coffee & Snack Packaging: Serves as the inner or middle layer in composite bags, providing excellent light, кислород, and moisture barriers to protect coffee aroma and snack crispness. Often laminated with matte films for a premium look.
• Млекарница & Butter Packaging: Used for individual wrapping of cheese slices and butter portions, preventing fat oxidation and extending shelf life.

3.2 Фармацевтско пакување: Guardian of Compliance and Safety

• Пакување со фармацевтски блистер: The most classic application. As the lidding material (backing foil)​ for PTP blisters, heat-sealed to PVC/PVDC forming films. Its excellent punching formability ensures tight blister edge seals, and its high barrier provides reliable protection for tablets, капсули, and suppositories. Typical thickness: 0.02-0.025мм.
• SP Strip Packaging: Used for strip packaging of granules/powders, also relying on 8011 foil’s precise heat-seal and barrier properties.
• Medical Device Sterilization Packaging: Laminated with materials like Tyvek® to create final sterile packaging bags, allowing sterilant (на пр., ethylene oxide) penetration while absolutely preventing microbial ingress.
