Under the dual pursuit of efficiency and quality in the packaging industry, the optimization of the production process of PET plastic pre-cut twist ties has become a core link for enterprises to enhance their competitiveness. From the perspectives of material selection, molding technology and quality control, this article analyzes how this product can achieve stable performance and controllable costs through a refined production process, while responding to environmental protection trends.
The performance of PET plastic directly affects the durability and environmental protection properties of twist ties, and its production needs to be strictly controlled from the raw material end:
a. Raw material quality control: Select PET particles that meet food grade standards to ensure the stability of twist ties in humid or low temperature environments and avoid brittle cracking caused by impurities.
b. Application of recycled materials: Under the premise of ensuring strength, gradually increase the proportion of recycled PET and reduce dependence on virgin plastics. For example, some companies reduce production costs and support the circular economy by adding recycled materials.
c. Optimization of functional additives: For different application scenarios (such as outdoor use), anti-ultraviolet agents can be added to extend the service life of twist ties.
The efficient production of pre-cut twist ties depends on mature molding technology:
a. Extrusion molding process: standard extrusion equipment is used to complete the melting and plasticization of PET materials, and efficiency is improved through continuous production.
b. Precision slitting technology: the mechanical slitting system is used to ensure the consistency of twist tie length, adapt to different packaging requirements, and reduce manual adjustment links.
c. Surface treatment optimization: simple processes (such as embossing) are used to enhance the friction between twist ties and packaging bags, reducing the risk of loosening during transportation.
Quality consistency is the key to the large-scale application of PET twist ties:
a. Physical performance test:
o Tensile strength test: Regularly check the tensile properties of twist ties to ensure that they meet basic packaging requirements.
o Resilience verification: Through repeated opening and closing tests, the recovery ability of the twist tie shape is tested.
b. Environmental adaptability verification:
o Conventional temperature and humidity tests to evaluate the durability of twist ties in different environments.
o Low temperature folding test to prevent breakage during transportation in cold areas.
c. Chemical safety testing: ensure that twist ties pass food contact material certification and comply with relevant regulatory requirements.
Production process optimization needs to take into account sustainability and economic benefits:
• Waste recycling: Recycle scraps and defective products in production for low-end product lines to improve resource utilization.
• Lightweight design: Reduce material usage through structural optimization, while maintaining strength and reducing production costs.
• Energy efficiency improvement: Optimize equipment operating parameters and reduce energy consumption in the production process.
Case: A manufacturer reduced the thickness of twist ties by adjusting mold design, reduced material consumption while ensuring performance, and saved about 10% of PET raw materials annually.
a. Intelligent production monitoring: Introduce basic sensors to monitor equipment operating status and optimize production parameters.
b. Low-carbon process exploration: Gradually reduce carbon emissions in the production process and adapt to environmental protection policy requirements.
c. Modular mold design: Flexibly adjust twist tie specifications to meet diverse order requirements.
The optimization of the production process of PET plastic pre-cut twist ties reflects the core logic of "lean management" in industrial manufacturing. Through material selection, molding technology improvement and quality control, enterprises can improve product performance and reduce production costs. For enterprises that want to strengthen the stability of the supply chain, cooperation with suppliers with mature production experience (such as Zhenjiang Hongda Daily Products Co., Ltd.) can quickly realize the implementation of technology and large-scale application.
