In the era of "dual carbon", the green transformation and compliance upgrade path of knife-type elastic pads

In the current era of comprehensive deepening of the dual-carbon strategy, green printing and sustainable packaging have become the core trends in the development of the printing and packaging industry. From the tightened environmental protection regulations at the national level, to the zero-carbon packaging requirements of brands, to the green trade barriers in export markets, the entire industrial chain is accelerating its transformation towards greening, low-carbonization, and compliance. And the knife plate spring pad, as the core supporting consumable in the die-cutting process, its environmental performance and compliance attributes are no longer just bonus items; they have become the market entry threshold for printing enterprises, and the key core for determining whether an enterprise can undertake high-end orders and break through green trade barriers.

For a long time, the development focus of the knife plate spring pad industry has been on performance indicators such as rebound, wear resistance, and precision. Environmental compliance issues have long been ignored, and there are many environmental pain points and compliance risks within the industry. In terms of formulation, a large number of low-price spring pads use recycled materials and inferior recycled rubber to produce, adding harmful additives such as heavy metals and phthalates, and the VOC emissions are seriously超标. Not only will this pollute the printed products， but it will also pose a hazard to the health of the operators in the production workshop. In terms of application， traditional spring pads mostly use non-recyclable thermosetting polyurethane formulas， which cannot be degraded or recycled after reaching their service life， and can only be incinerated or landfilled as industrial solid waste， causing a large amount of resource waste and increasing the carbon footprint and environmental disposal costs of the enterprise. In terms of production， some small-scale manufacturers adopt a loose intermittent foaming process， with high energy consumption in the production process and non-compliant emissions of waste gas and wastewater， not meeting the requirements of green factories， and facing compliance risks in environmental protection supervision. In terms of compliance， most products do not have complete food contact material certifications or environmental testing reports， unable to meet the compliance requirements of food and pharmaceutical packaging， and unable to adapt to international environmental protection standards such as EU REACH and US FDA， becoming the core weakness for enterprises to undertake high-end orders and expand export markets.

These overlooked environmental compliance issues are causing increasing operational risks for printing enterprises. For packaging orders for food， medicine， and baby products， the country mandates that all consumables in the packaging production process must comply with food contact material safety standards. If non-compliant knife plate spring pads are used， problems such as debris shedding and harmful substances leaching will occur， resulting in不合格 inspections of the finished products. Enterprises will not only face huge fines but also may have their production qualifications revoked， and even bear legal responsibilities. For export orders， if the spring pads do not comply with EU REACH， RoHS， etc. environmental regulations， the entire batch of goods will be returned or detained， causing huge economic losses to the enterprise. Under the dual-carbon goal， more and more leading brand owners require suppliers to provide carbon footprint reports for the entire product life cycle. Using non-recyclable and high-carbon-emission spring pads will prevent enterprises from meeting the low-carbon requirements of brand owners and losing the qualification for high-end order cooperation.

Facing increasingly strict environmental requirements and market trends， the green transformation of the knife plate spring pad industry is imperative. Leading enterprises have taken the lead in action， from the four dimensions of formulation， production， application， and compliance， building a complete green upgrade path， guiding the industry's development.

In the environmental upgrade of the formulation system， the core is to achieve the dual goals of "safety compliance + recyclability". For scenarios with high compliance requirements such as food and medicine packaging， leading enterprises have developed food-grade environmental formulations， using high-purity new raw materials， without heavy metals， plasticizers， aromatic amines， and high VOC emissions. The products have passed GB 4806 food contact material safety certification， US FDA certification， and EU food contact material standard testing， and can be directly applied to packaging die-cutting in sensitive fields such as food， medicine， and baby products， completely eliminating compliance risks. In response to the circular requirements of the dual-carbon era, enterprises have broken through the technical limitations of traditional thermosetting polyurethane and developed recyclable thermoplastic polyurethane cushioning materials. After the products reach their service life, they can be recycled, ground into particles, and reformed to achieve recycling. The performance retention rate of the recycled and regenerated materials can reach over 80%. This has achieved a closed-loop recycling of resources and significantly reduced solid waste emissions and the carbon footprint throughout the product's life cycle.

In terms of the green upgrade of the production process, the core is to achieve "low energy consumption + low emissions" through clean production.
