Compare Insert Materials by Product and Packing Needs

The right insert depends on your product’s weight, shape, fragility, presentation and shipping method. Compare the options below to identify a suitable material and structure before sampling.
EVA foam insert for skincare and electronics packaging
EVA Foam Inserts

A firm, precision-cut option for fragile or high-value products that need secure positioning. Often used for glass bottles, electronics and premium gift sets.

Colored PU foam insert for flexible cushioning and shaped packaging
PU and PE Foam Inserts

Choose softer PU foam for cushioning or firmer PE foam for shape retention and repeated handling. Both can be cut around irregular products and multi-piece kits.

Corrugated box insert made with fluted cardboard for makeup or kits
Corrugated Box Inserts

Corrugated inserts add structural support without the weight of solid foam. A practical choice for heavier products, multi-item packs and products prepared for shipping.

Molded pulp insert inside sustainable box with insert
Molded Pulp Inserts

A fiber-based option shaped around the product for protection and presentation. Suitable when reducing plastic is a priority and the product design supports molded tooling.

Transparent PET insert for food-safe or display packaging
PET and PP Plastic Inserts

Thermoformed PET or PP trays provide accurate cavities and a clean presentation for food, beauty and consumer products. Food-contact grades and supporting documentation can be specified when required.

PS insert tray for electronic accessories or display trays
PS Trays

A lightweight thermoformed option for precise product placement and clear or colored presentation. Heat resistance, impact performance and recycling requirements should be reviewed before selection.

Cardboard insert for eco-friendly gift and beauty sets
Die-Cut Paperboard Inserts

Folded paperboard can hold lightweight products while keeping the packaging compact and printable. Commonly used for tubes, small bottles, confectionery and gift sets.

Pre-folded tray insert for mailer box packaging
Folded Insert Trays

Pre-folded or self-locking trays can simplify assembly and reduce the need for separate foam components. Useful for mailer boxes and products requiring fast, repeatable packing.

What the Right Insert Should Solve

A packaging insert should do more than fill empty space. Its structure should control product movement, simplify packing and present each item clearly when the box is opened.

Keep Products Secure in Transit

A fitted insert limits movement inside the box and supports fragile or heavy areas of the product. The structure can be tested for pressure, removal space and box closure before full production, helping reduce breakage, repacking and avoidable returns.

Organize Every Item for a Cleaner Presentation

For gift sets and multi-product kits, a custom insert gives each item a defined position and keeps the arrangement consistent during packing. Separate cavities can also make products easier to identify, remove and replace.

Reduce Plastic with Paper-Based Structures

Folded paperboard, corrugated board and molded pulp can replace foam or thermoformed plastic in suitable projects. The final choice should account for product weight, fragility, presentation requirements and the recycling system in the destination market.

Not Sure Which Insert Structure to Choose?

Start with your product dimensions, weight, fragile areas, outer-box size and packing method. These details help determine whether molded pulp, foam or a paper-based structure is the most practical option for sampling.

What Your Insert Project Includes：

From Product Measurements to a Production-Ready Insert

Insert Structure Developed Around Your Product

Product dimensions, weight, fragile areas and removal space are considered when developing the cavity layout and supporting structure.

Material Options Compared for the Same Application

Foam, paperboard, corrugated board, molded pulp and plastic trays can be compared according to protection, presentation, packing and recycling requirements.

Insert and Outer Box Planned Together

The insert height, wall clearance and product position are coordinated with the outer box to prevent poor closure, loose fitting and unnecessary empty space.

Order Quantities Matched to the Insert Process

Suitable production quantities depend on the material, tooling and structure. Available options can be compared before sampling so the insert fits both the product and purchasing plan.

Sampling and Production Checks：

Check the Fit Before Committing to Production

Structural Samples in About Three Working Days

Once the product dimensions and structure are confirmed, a sample can usually be prepared in about three working days for fit and assembly review.

Product Movement and Removal Check

The sample is checked for unwanted movement, excessive pressure and sufficient finger space so the product stays secure without becoming difficult to remove.

Box Closure and Packing Check

Insert height, product position and packing sequence are reviewed to confirm that the outer box closes correctly and can be packed consistently.

Approved Specifications Recorded for Production

The approved material, cavity dimensions, structure and assembly details are recorded to reduce variation during production and repeat orders.

    Parfume

    We ordered fragrance labels with very detailed colors and many SKU. Emma's team nailed the shades exactly. Not easy, but they made it look easy.

      Retail Chain

      We had a tight event deadline and needed branded labels, brochure and vip membership cards fastly. Got them earlier than promised. Saved us a headache.

        Body Care

        We had no idea which material is better for our proudc, and how label finish affects body product bottles. They explained lamination vs. varnish patiently. That's not common.

          Skincare

          Designing skincare labels in small batches is often tricky. Here it wasn't. Flexible, responsive, and quality was consistent.

          The Questions Buyers Ask Before Ordering Custom Box Inserts

          Yes. You can start with your product dimensions, weight, photos and the inside dimensions of the box. For an irregularly shaped product or a cavity that requires a close fit, sending us the actual product is more reliable. We can then create and adjust the insert structure before production.
          Yes. We can develop an insert for an existing box, even if the box comes from another supplier. You can provide its dieline, accurate inside dimensions or a physical sample. We will also check the board thickness and usable space to make sure the insert fits without bending or distorting the box.
          We size each cavity around the product, allowing for normal variation in both the product and insert material. During sampling, we check movement, pressure points, finger space and box closure. For fragile or irregularly shaped products, testing the insert with the actual item gives the most reliable result.
          Yes, if the products can share the same outer-box size without leaving excessive empty space. Different insert layouts can accommodate changes in product shape, height or arrangement. We compare the products first to confirm that a shared box will still provide secure support and a consistent presentation.
          That depends on the structure and how your team packs the products. Self-locking paperboard and corrugated inserts can often ship flat to reduce freight space. More complex or glued inserts may be easier to use when supplied preassembled. Sampling can help compare assembly time, packing consistency and shipping volume.
          We produce against the approved sample, dieline and material specifications. During production, we check key cavity dimensions, material thickness, cutting accuracy and assembly. We also keep the approved specifications for repeat orders so any material or structural change can be reviewed before production begins.
