BOPA film can be widely applied for the flexible packaging of food, daily-uses, chemicals, electronic products, etc. with its multi-performances. According to the applications, we can divide them into the following parts.

PART 1. Food Package

1. 1.     General Package

• Typical lamination structure: BOPA//PE
• Some specific applications: jelly, bread.
• Performances required: the requirements in printing are more complicated , and in frame pairing is more higher. Vacuum package should have good impact resistance.

1. 2.     Frozen Food Package

• Typical lamination structure: BOPA//PE
• Some specific applications: frozen dumpling, frozen meat.
• Performances required: low temperature resistance, good flexibility, puncture resistance, etc..

1. 3.     Retort Package

• Typical lamination structure: BOPA//CPP, BOPA//RCPP, BOPA//AL//RCPP
• Some specific applications: flammulina velutipes, bamboo shoots, bean products, beef, etc..
• Performances required: the requirements in printing are more complicated , in frame pairing is more higher, and also can be sterilized. The inner layer should be choose the CPP or RCPP film.

1. 4.     Zongzi Package

• Typical lamination structure: BOPA-15mic//BOPA-25mic//RCPP, BOPA-25mic//RCPP
• Performances required: ① BOPA film with both corona treatment. ② High mechanical strength property. ③ Good tensile strength and impact resistance. ④ The adhesive should be a two-component polyurethane adhesive capable of withstanding high temperature ＞ 135 ℃, with solid content of 35 ~ 40%. ⑤ The inner layer should be RCPP withstanding high temperature retort ＞ 135℃.

1. 5.     Heavy Package
