Manufacturing Premium Aluminum Foil Bags Begins with Selecting Premium Raw Materials

Superior products originate from superior materials.

1. 100% Virgin Polyethylene Resin

Shenzhen Huazhong Printing Co., Ltd. has consistently used 100% virgin polyethylene resin for years. Products manufactured from 100% virgin material are odorless, colorless, exhibit excellent gloss, and meet hygiene and safety standards. PE films produced through virgin resin blow molding demonstrate superior tensile strength, enhanced physical properties, and better anti-aging performance.

Most manufacturers opt for recycled materials to reduce costs. However, recycled resin sources are inconsistent, contain impurities, and undergo uneven cleaning and processing, resulting in unstable PE film quality that significantly compromises tensile strength and anti-aging properties.

During hot packaging, impurities from recycled PE films may contaminate the contents. This poses particular risks for electronic products or circuit boards, potentially causing oxidation and short circuits. Therefore, the inner PE film of aluminum foil pouches is critical. High-strength PE films with excellent heat-seal properties minimize bag breakage.

2. PET Film, Nylon Film, and Aluminum Foil Film

PET film, nylon (PA) film, and aluminum foil (AL) film should be sourced from top-tier manufacturers.
