Tropical bliral folil a me ke anu-collad blister blister folis he mau lāʻau lapaʻauʻelua, ʻO ka laulā i kapaʻiaʻo ia e like me ka alumini alumini a me ke anuanu. Hoʻohana maʻamauʻo Aluminim metala 1000 moʻo 8000 moʻo (8011 8021), although both of them are used for pharmaceutical packaging, but they are very different in material.

Tropical aluminum is a composite of nylon and pure aluminum. The cold aluminum is made of nylon, AL ALMInim, and pvc. PA/AL is also compounded with adhesive. AL needs to be coated with adhesive (VC) to be heat-sealed with PVC, so tropical aluminum is also expressed as PA/AL/VC. The medicine is packaged into: PA/AL + PVC + PTP, and the medicine is between the PVC bubble and PTP.

Cold aluminum: Each layer is compounded with adhesive, and the structure is PA/AL/PVC. When using, the PVC layer is heat-sealed with the adhesive (VC) on the PTP; the medicine packaging method is: PA/AL/PVC + PTP, and the medicine is between the PA/AL/PVC foam and the PTP.

The biggest difference between the two is that tropical aluminum is used for heat sealing with pvc, while cold aluminum is directly used for charging.
