摘要

目的针对乳制品内包装用缓冲垫片的开发需求,系统评述纸浆模塑材质替代传统EPS泡沫塑料的技术路径与产业化价值,旨在应对全球“限塑令”持续推进及消费者环保意识增强所带来的包装材料转型压力,为乳制品包装向绿色化、高端化方向升级提供理论依据。方法聚焦于普通工业包装中的运输（缓冲）包装范畴,通过梳理植物纤维原料微观结构特征与成型工艺参数的相关研究,分析纸浆模塑材料力学性能的形成机制;归纳内外件叠合结构、加强筋布局优化、杯形空腔缓冲机制等结构设计理念,总结满足乳制品定位保护需求的系列化缓冲垫片结构方案并对材料性能、结构效率与成本经济性进行综合评估。结果现有文献表明,纸浆模塑材料在轻量化（密度0.3~0.8 g/cm³）、可折叠性（仓储空间节约40%以上）和缓冲性能（能量吸收系数达0.65~0.75）方面表现突出。相比EPS泡沫,其在复杂异形产品定位、品牌价值提升和消费者体验方面具有不可替代性。同时,可降低采购成本15%~25%并具备形成专利技术壁垒的潜力。结论综合分析认为,纸浆模塑缓冲垫片不仅能够有效替代EPS泡沫以满足环保合规要求,而且可在仓储效率、成本控制和品牌差异化等方面为企业创造综合竞争优势,从而推动乳品包装行业实现绿色、高端转型升级。

Abstract

The work aims to systematically review the technical pathways and industrial value of replacing traditional EPS foam with molded pulp materials for the development of inner cushioning pads in dairy product packaging, in response to the ongoing global plastic restriction directives and increasing consumer environmental awareness, and provide a theoretical basis for upgrading dairy packaging towards greener and higher-end solutions. Focusing on the category of transport cushioning packaging in ordinary industrial packaging, by synthesizing studies on the microstructural characteristics of plant fibers and process parameters of molding, the formation mechanisms of the mechanical properties of molded pulp materials were analyzed. Structural design concepts, including nested inner-outer structures, optimized rib layouts, and cup-shaped cavity cushioning mechanisms, were summarized to propose a series of cushioning pad configurations that met the positioning and protection requirements of dairy products. A comprehensive evaluation was conducted regarding material properties, structural efficiency, and cost-effectiveness. Existing literature indicated that molded pulp exhibited outstanding lightweight properties (density 0.3-0.8 g/cm³), foldability (saving >40% in storage space), and cushioning performance (energy absorption coefficient 0.65-0.75). Compared with EPS foam, molded pulp offered irreplaceable advantages in positioning complex-shaped products, enhancing brand value, and improving consumer experience. Additionally, it could reduce procurement costs by 15%-25% and held potential for establishing intellectual property barriers. The comprehensive analysis concludes that molded pulp cushioning pads can effectively replace EPS foam to meet environmental compliance requirements, while creating comprehensive competitive advantages for enterprises in terms of storage efficiency, cost control, and brand differentiation. Thus, they can drive the green and high-end transformation and upgrading of the dairy packaging industry.
