In response to the global demand for environmentally friendly packaging, our company's packaging machine degradable material heat sealing process laboratory was officially put into use recently. The laboratory focuses on the in-depth adaptation research of degradable film materials and heat sealing technology, is committed to solving industry pain points, and promotes the upgrading of packaging equipment to high efficiency and low carbon, providing more sustainable solutions for food, daily chemicals, medical and other fields.
R&D background: Solving the problem of heat sealing of degradable materials
With the advancement of the "plastic restriction order" policy and the improvement of consumer environmental awareness, degradable materials such as PLA and PBAT are increasingly widely used in the packaging field. However, the traditional packaging machine heat sealing process often faces problems such as low melting point of degradable film materials, insufficient heat sealing strength, and easy cracking, which makes it difficult to balance packaging efficiency and finished product qualification rate. The opening of the new laboratory will systematically overcome the adaptation bottleneck of degradable materials and heat sealing technology, and help customers achieve green transformation.
Technical highlights: precise temperature control and process innovation
Relying on an advanced simulation test platform, the laboratory can optimize the heat sealing process parameters of the packaging machine according to the characteristics of different degradable materials (such as temperature resistance range, ductility, and degradation cycle). Through core technologies such as dynamic temperature compensation and multi-stage pressure regulation, the uniformity and stability of the heat-sealed seams are significantly improved to ensure that the packaging sealing strength meets the requirements of long-distance transportation and warehousing. At the same time, the laboratory has also developed a low-energy heat-sealing module to reduce energy consumption while ensuring performance, which is in line with the company's sustainable development goals.
Application scenarios: Covering green packaging needs in multiple industries
The laboratory's research results will directly enable packaging equipment upgrades. For example, in the food industry, the optimized packaging machine heat-sealing process can be adapted to PLA pre-prepared food packaging to avoid material deformation caused by high-temperature sealing; in the field of daily chemicals, for PBAT laundry beads packaging, the heat-sealing process can effectively balance the sealing speed and breakage rate, and improve production line efficiency. In addition, the laboratory can also provide customers with customized heat-sealing solution testing services to shorten the new product development cycle.
Industry value: Promote the construction of green packaging ecology
"The heat sealing process of degradable materials is a key link in the upgrade of packaging equipment." The head of the laboratory said, "By continuously optimizing the heat sealing process of packaging machines, we can not only help customers reduce material loss and improve the yield rate, but also accelerate the large-scale application of degradable packaging and reduce plastic pollution." In the future, the laboratory will work with upstream and downstream companies to jointly explore innovative directions such as bio-based materials and circular packaging, and provide the industry with feasible environmental protection technology support.
