15g 4-Layer PET/AL/NY/PE Oil-Barrier Botanical Paste Stick Pack vs Glass Jar vs Blister Cup Co-Packing
When co-packing oil-rich herbal pastes containing cold-pressed black sesame oil and ginger essential oils, standard 3-layer PET/AL/PE film suffers from adhesive delamination and seal-edge oil seepage within 45 days. YONG FOOD engineers a 110-micron 4-layer composite laminate (PET 12um / AL 7um / BOPA Nylon 15um / Modified Metallocene PE 76um) with ultrasonic hot-tack sealing, delivering zero oil migration at 40°C accelerated aging while reducing air-freight weight by 68% compared to glass jars.
