The inner liner of the
packaging box is a crucial component for protecting the product from vibrations, impacts and friction during transportation and storage. As brands' requirements for packaging experience have risen, the inner liner is no longer just a "filler", but has evolved into a customized solution that combines functionality (buffering, fixation), aesthetics (fitting the design, enhancing the texture) and sustainability (using eco-friendly materials).?

Enhances brand image: Can be integrated with brand elements through surface treatments (such as gold stamping, UV printing), demonstrating the enterprise's sense of responsibility and aesthetic taste.?
?
When choosing the inner lining material for paper custom packaging boxes, one should consider the product's characteristics, packaging requirements, and environmental protection standards comprehensively. The kraft paper lining bag is suitable for food and cosmetic packaging that emphasizes environmental protection and aesthetics; cardstock or corrugated paper lining is suitable for electronic products and wine packaging that are cost-sensitive and require good cushioning performance; white lining paper is suitable for jewelry, food, and cosmetic packaging that requires high-end texture and good barrier performance. Each material has its own unique advantages and applicable scenarios. Making a reasonable choice can enhance the overall quality of the product and its market competitiveness.?
?
Customized foam packaging box liner
A customized foam packaging box liner refers to an internal filling structure tailored to the shape of the product. Common materials include EPS (polystyrene), EPE (pearl cotton), EVA, PU, etc. This type of liner precisely fits the contours of the items, effectively absorbing impact forces and preventing damage during transportation. With the complexity of logistics environments and the increasing demand from consumers for product integrity, customized liners have become an important component of high-end packaging.?

?
Potential drawbacks
High environmental pressure: Traditional EPS foam is difficult to decompose naturally and incineration may release harmful gases, which does not meet the requirements of some countries' environmental regulations.
Inefficient recycling system: Although technically recyclable and reusable, the actual recycling cost is high and the classification is difficult, resulting in a large amount of waste foam being sent to landfills.
Static electricity risk: Ordinary foam is prone to generating static electricity, which may damage electronic components, so anti-static agents need to be added for improvement.
Space occupation: Before compression, the volume is large, which reduces the efficiency of storage and transportation, and increases the carbon footprint.?
?
Plastic customized packaging box liner
The liner inside the packaging box is a key component for product protection, especially playing a role in shock prevention, scratch resistance, fixation and enhancing the texture during transportation and display. Plastic liners, due to their strong customizability, high forming accuracy and controllable cost, have become the preferred choice for packaging of high-end or precision products. Different plastic materials have different physical and chemical properties, and the suitable application scenarios also vary.?
