A Brief Discussion on How to Prevent Over‑Hardening in Plastic Bag Processing
Plastic packaging bag manufacturers advise that extra care should be taken during the final stages of production, as products can harden if not handled properly. This issue arises from improper formulation ratios. Today, we’ll learn how to prevent such hardening.
Qingdao Platinum Packaging Technology Co., Ltd. is a manufacturing enterprise specializing in plastic flexible packaging, encompassing the research and development of new plastic materials, printing, laminating, slitting, bag-making, and related R&D. The company’s production base is located in the Jiaobei Industrial Park, Jiaozhou City, Qingdao, while its business operations and R&D center are situated in the Shinan District of Qingdao. With many years of experience, the company produces high‑quality plastic flexible packaging materials and comprehensive packaging solutions. Its main product lines include: laminated plastic packaging bags, color‑printed packaging bags, food‑grade packaging bags, vacuum‑sealed bags, retort pouches, low‑temperature frozen‑food bags, cat litter bags, and rolls of automatic packaging films for food and medical applications; as well as transfer printing films, warning tapes, flagging tapes, bird‑deterrent tapes, and cable ties for air conditioners, among others.

First, the formulation ratio must be strictly controlled. If maintaining the correct ratio proves difficult, a lifting device can be used to prevent the plastic bags from becoming excessively rigid due to uneven mixing. Should this issue persist, it may indicate an underlying problem with the product formulation, requiring several adjustments. Additionally, softening agents can be incorporated into the masterbatch to reduce the stiffness of the packaging bags.
Secondly, the materials used to manufacture the product are non‑degradable; therefore, to protect the environment, used products can be placed in designated recycling stations, ensuring that their performance remains intact.
