Gift Box Inserts: 5 Types Compared – EVA / EPE / Sponge / Cardboard / Blister

Last month, a client who makes high-end watch gift boxes contacted me. Their new watch is priced at 5,800 RMB, with an overall gift box budget of 35 RMB. When I asked him what insert he had chosen, he looked blank: "I never thought about it — whatever the printing factory recommends." After we worked through the costs, we found the insert alone ate up 12 RMB — more than one-third of the gift box cost.

This case is actually very typical. The gift box insert is the most easily overlooked item in procurement. Printing factories often mention it in passing in their quotes ("insert priced separately by material"), and clients often overlook it when signing the contract. But the choice of insert material directly determines three core dimensions of the gift box: protection, visual texture, and cost structure.

Type 1: EVA Insert — The "Default Option" for High-End Gift Boxes

EVA is ethylene-vinyl acetate copolymer, with an appearance similar to rigid foam. The surface can be finished with flocking fabric, PU leather wrap, or flocking. Unit price 0.3-0.6 RMB/unit, minimum order quantity 100 units per batch, tooling fee 800-3,000 RMB.

EVA is the most common insert material in high-end gift boxes, mainly because it can deliver 4 different surface textures: ① bare EVA (lowest cost); ② flocking fabric laminated EVA (+0.15-0.30 RMB); ③ PU leather wrapped EVA (+0.40-0.80 RMB); ④ flocked EVA (+0.50-1.00 RMB).

EVA's advantage is low tooling cost — laser or CNC mold cutting is 800-3,000 RMB, 30-50 times cheaper than blister tooling. This makes EVA particularly suitable for small-batch custom gift boxes of 500-5,000 units.

EVA's disadvantage is environmental pressure. EVA itself is a petroleum-based, non-biodegradable material, and EU EPR (Extended Producer Responsibility) regulations are imposing increasingly strict recycling deposit requirements on EVA inserts. If gift boxes are to be exported to the EU, consider switching to recycled EVA or water-based adhesive lamination.

Type 2: EPE Insert — The Strongest Protection

EPE is polyethylene foam, commonly known as "pearl cotton," with a white or black foam bead structure. Unit price 0.15-0.40 RMB/unit, minimum order quantity 50 units per batch, virtually no tooling fee (die-cut to product dimensions).

EPE's core advantage is compression and cushioning performance. A 1 cm thick EPE can withstand 5 kg of static pressure without deformation. Among all insert materials, EPE offers the strongest impact resistance, making it especially suitable for fragile items (glass bottles, ceramics, electronic products).

EPE's disadvantage is visual texture. EPE has a strong granular surface; even with flocking fabric or paper laminated on, the texture is still not as refined as EVA. Mid-to-high-end gift boxes (priced above 200 RMB) rarely use EPE as inserts — EPE is mainly used for industrial products and electronics.

Type 3: Sponge Insert — The Cheapest Option

Sponge is polyurethane (PU) foam, soft and porous in appearance. Unit price 0.08-0.20 RMB/unit, minimum order quantity 50 units per batch, tooling fee 0 RMB (die-cut or stamped to size).

Sponge is the cheapest of the 5 insert materials and the most common low-end gift box accessory. But sponge has several critical flaws: ① poor resilience — visible compression marks after 6-12 months of use; ② low heat resistance (deforms above 60℃); ③ sheds crumbs (dust contaminates the product).

Sponge inserts are mainly used in the following scenarios: ① e-commerce low-price gift boxes (single item total price < 50 RMB); ② jewelry boxes, cosmetic sample packaging; ③ single-use holiday gift boxes (Dragon Boat Festival, Mid-Autumn Festival, Spring Festival).

Type 4: Cardboard Insert — The Most Eco-Friendly but Weakest Protection

Cardboard inserts are made from heavyweight cardboard (350-600 g) through die-cutting, folding, and gluing. Unit price 0.15-0.35 RMB/unit, minimum order quantity 100 units per batch, tooling fee 500-2,000 RMB (die-cut plate).

The core advantage of cardboard inserts is recyclability, biodegradability, and printability. Cardboard itself supports 4-color printing, allowing brand stories, care instructions, or product traceability QR codes to be printed inside the gift box. None of the other 4 insert materials can match this.

But cardboard inserts have weak protection — compression and impact resistance are far lower than EVA / EPE / sponge. If the product is fragile (glass bottles, ceramics, precision electronics), cardboard inserts alone are not recommended. A "cardboard + sponge" double-layer structure can be used: the outer cardboard layer handles display and printing, while the inner sponge layer handles protection.

Type 5: Blister Insert — The "Industrial-Grade" Choice for Large-Volume Orders

Blister inserts are made from plastic sheets (PVC, PET, PP) through thermoforming. Unit price 0.8-1.5 RMB/unit, but tooling fee 80,000-150,000 RMB.

Blister's biggest advantage is the lowest unit price at high volumes. Although tooling fees are expensive, when amortized over orders of 100,000+ units, the per-unit tooling cost becomes negligible. The unit price is actually 20-30% lower than EVA.

Blister's disadvantage is the minimum order threshold. For orders under 8,000-10,000 units, blister tooling is not recommended because the tooling fee cannot be amortized. Blister should only be considered for orders of 10,000+ units.

Blister is mainly used in the following scenarios: ① cosmetics mass packaging (lipstick, compact, perfume bottle inserts); ② electronic accessories (phone cases, data cables, earphones); ③ mass-produced food gift boxes (chocolate, mooncake inserts).

How to Choose Among the 5 Insert Types?

The selection logic is simple: look at order quantity, product protection level, and budget.

3 Details Not Shown on the Printer's Quote

First, EVA density. Industry quotes only mention "EVA insert" without specifying density, but the hand feel differs dramatically between 38 kg/m³ and 55 kg/m³ EVA. Recommend specifying in the contract: "EVA density ≥ 45 kg/m³."

Second, cardboard grammage. 350 g and 600 g cardboard differ in price by 30%. Recommend specifying in the contract: "cardboard grammage ≥ 400 g," to prevent the printer from substituting inferior materials.

Third, blister material. PVC is cheap but contains chlorine and is restricted in the EU; PET is eco-friendly but 30% more expensive; PP offers the best value. Recommend specifying in the contract: "blister material PET or PP, PVC not accepted."
