Overview of Packaging Insert Materials
01 - EVA Material Insert
Characteristics: Good flexibility, rubber-like elasticity, remains flexible at -50°C, high transparency and surface gloss, excellent chemical stability, anti-aging and ozone resistance, non-toxic. Available in Grades A, B, and C with thicknesses ranging from 0.5mm to 50mm. Features moisture-proof, shock-proof, and compression-resistant properties.
Applications: Commonly used for high-end boutique boxes, such as packaging for cosmetics, watches, jewelry, healthcare products, luxury goods, etc.
02 - EPE Pearl Cotton Insert
Characteristics: Made from recycled polyethylene foam. While its eco-friendliness is slightly lower than EVA and XPE, it features large air cells, low density, and high affordability. It offers advantages like environmental protection, anti-static, heat insulation, anti-collision, compression resistance, and corrosion resistance, with excellent chemical resistance. Odorless, and can be laminated with flocked cardstock or specialty papers.
Applications: Widely used in the packaging of eggs, electronic appliances, glass products, fresh fruits and vegetables, cosmetics, and other products.
03 - XPE Material Insert
Characteristics: Virgin granules foamed without additives, fully eco-friendly material with a smooth surface, small air cells, high density, and high resilience. Slightly rigid and resistant to deformation, featuring insulation sealing, water resistance, corrosion resistance, environmental protection, and shock-proof properties. Similar to pearl cotton, its primary material is polyethylene, produced through high-temperature physical foaming, resulting in a smooth and aesthetic texture.
Applications: Suitable for packaging hardware tools, power tools, tea, cosmetics, perfume, fragile glass products, etc.
04 - Blister Insert
Characteristics: Formed by heating and softening flat plastic rigid sheets, then using vacuum suction to adhere them to the mold surface, followed by cooling. It provides strong protection for products and can be made into various shapes. Highly adaptable, with good transparency, plasticity, and low-temperature resistance. Features lower costs, though its structural protection is relatively lower compared to rigid materials.
Applications: Commonly used in food packaging such as mooncake tins, candy tins, cookie tins, as well as in electronics, cosmetics, digital products, and other fields.
05 - Sponge Material Insert
Characteristics: The original color of the sponge is off-white, which may turn yellow over time due to oxidation with oxygen. Soft texture with excellent shock-proof and thermal insulation properties. Can be molded into various shapes as needed. Provides cushioning, fixing, and protection for products, preventing damage caused by vibration or collision during transportation or storage.
Applications: Widely applicable to various packaging inserts, such as tins for watches, perfumes, pharmaceuticals, cosmetics, and other bottled fragile products.
06 - Cardboard Material Insert
Characteristics: A common cushioning material in packaging that is cost-effective and aesthetically pleasing. Provides cushioning, fixing, and protection for products, preventing damage caused by vibration or collision during transportation or storage.
Applications: Commonly used for packaging food, electronics, cosmetics, or incense products. Cardboard liners provide a certain level of protection and support printing processes to enhance product grade and texture, such as white cardboard, kraft paper, gold/silver cardboard, etc., enabling multiple printing techniques to elevate packaging quality.
07 - Corrugated Board Material Insert
Characteristics: Made from multiple layers of paperboard bonded together, featuring strong folding resistance, anti-aging, and high load-bearing capacity. Excellent performance in tensile strength, compression, tearing, and temperature resistance. Formed through die-cutting, creasing, and gluing. Offers advantages like low cost, lightweight, good cushioning, durability, and ease of storage and handling. As a green and eco-friendly product, it is widely used for food or digital product packaging.
Applications: Suitable for packaging in the electronics, food, pharmaceutical, and other industries.
08 - Foam Material Insert
Characteristics: Easy to process and mold, lightweight, and convenient for transportation and carrying. Superior cushioning performance, as it can absorb energy through its own deformation when impacted, protecting the packaged items. Additionally, it has good thermal insulation to maintain internal temperature stability. Stable chemical properties, resistant to environmental influences, and non-toxic. Can be customized according to product shapes and sizes for precise fit and comprehensive protection.
Applications: Used in electronic products, glass products, precision instruments, and other fields.
09 - Pulp Tray
Characteristics: Made from plant fibers as raw materials through compression molding or injection molding techniques. It is a highly popular modern insert material. Features low cost, strong impact resistance, excellent shock-proofing, and good lining effects. Eco-friendly, biodegradable, and pollution-free to the environment.
Applications: Relatively coarse texture, generally used for large fragile items and digital product packaging, such as electronics, appliances, ceramic crafts, pharmaceuticals, etc.
10 - Silk Lining
Characteristics: Silk cloth is a fabric woven with silk as the primary raw material. It features a lightweight, soft texture with a smooth and glossy surface, presenting an elegant and luxurious visual effect. It has a unique texture and feel, providing a high-end and exquisite impression.
Applications: Used as an inner lining material for high-end products and gift packaging to enhance product grade and aesthetics. Common in packaging for high-end gifts, luxury goods, traditional handicrafts, advanced silk products, etc.
11 - Raffia Paper Insert
Characteristics: Also known as wishing rope or love grass, raffia originates from Madagascar, Africa. It is a natural plant fiber material. As an imported high-grade material, it is recognized internationally for its strong toughness and exceptional quality. Often woven into specific shapes or used as loose filler in packaging boxes.
Applications: Suitable for packaging exquisite products like specialty gifts, jewelry, skincare products, tea, handicrafts, high-end agricultural products, wedding and holiday gifts.
12 - Paperboard Material Insert
Characteristics: Usually made from fiber raw materials such as wood fiber or recycled fiber. It has a certain degree of stiffness and can withstand some pressure. For example, a single sheet of paperboard can serve as a support for lighter products like small stationery or greeting cards, preventing them from moving within the packaging.
Applications: Packaging for snacks like cookies and chocolates, and small electronic products like headphones and power banks.
13 - Corrugated Insert with Face Paper
Characteristics: Corrugated medium provides good cushioning to absorb and disperse external impacts, effectively reducing product damage during transportation. The face paper provides a smooth and aesthetic surface, facilitating printing and display of product information.
Applications: Packaging for large home appliances like TVs and refrigerators; and fragile items like glass cups, vases, ceramics, tableware, handicrafts, etc.
