Custom EVA Foam & Cardboard Inserts for Premium Packaging

Precision-Fit Protective Inserts for Vials, Skincare Products & Gift Boxes

Custom Peptide EVA Foam & Cardboard Inserts provide a practical way to organize, position, and protect products inside branded packaging boxes.

Designed for glass vials, cosmetic bottles, skincare ampoules, small accessories, and multi-component kits, these inserts can be customized to match individual product dimensions and packaging requirements.

Choose from precision-cut EVA foam, printed paperboard, kraft cardboard, or corrugated inserts depending on your protection requirements, packaging style, and budget.

Whether you are developing a premium skincare collection, laboratory sample kit, or wholesale product packaging system, a properly designed insert creates a more organized product presentation while reducing unnecessary movement inside the box.

1. Custom EVA Foam Inserts

EVA foam inserts are suitable for products that require cushioning, stable positioning, and carefully shaped cavities.

The closed-cell foam structure offers a flexible combination of resilience and dimensional support. Cutting profiles can be developed around circular, rectangular, or irregularly shaped products.

Recommended EVA Foam Specifications

• Material: Closed-cell Ethylene Vinyl Acetate (EVA)
• Reference density options: 30, 40, and 50 kg/m³
• Design thickness: Custom, with 10–30 mm as an initial project reference
• Colors: Black, white, gray, or project-specific colors
• Cutting: Die cutting or CNC contour cutting
• Configurations: Single cavity, multiple cavities, layered inserts, and integrated accessory compartments

Actual density and thickness should be selected according to the product weight, required cavity depth, and packaging tests.

Suitable EVA Packaging Applications

EVA foam inserts can be developed for:

• 2 mL, 3 mL, 5 mL, and 10 mL laboratory vials
• Glass skincare ampoules and serum bottles
• Cosmetic sample and discovery kits
• Premium rigid gift boxes
• Fragile accessories and small instruments
• Multi-vial packaging and branded presentation sets

Each cavity should be designed using the actual product dimensions, including the body diameter, cap diameter, total height, and removal clearance.

2. Custom Cardboard & Paperboard Inserts

Cardboard inserts provide an alternative for brands seeking printable internal packaging structures.

They can be die-cut, folded, and assembled into platforms, separators, and individual product compartments.

For many packaging projects, 300–400 gsm SBS white paperboard or kraft paperboard provides a practical starting point.

Corrugated structures may also be evaluated when additional support or separation is required.

Recommended Cardboard Specifications

• Material: SBS white paperboard or natural kraft paperboard
• Reference weight: 300–400 gsm
• Optional structure: E-flute or B-flute corrugated board
• Printing: CMYK full-color or Pantone spot colors
• Finishing: Matte lamination, gloss lamination, or selected specialty finishes
• Construction: Die-cut platforms, folded holders, partitions, and bottle supports

Cardboard inserts can also carry printed branding, product identifiers, and instructions on visible surfaces.

They are particularly suitable for cosmetic gift sets, folding cartons, retail packaging, and subscription boxes.

3. Custom Cavity Design & Product Protection

An effective packaging insert must fit both the product and its outer box.

A typical customization project begins with three sets of measurements:

Product Dimensions

Measure the overall length, width, height, bottle diameter, cap dimensions, and product weight.

Outer Box Dimensions

Provide the usable internal length, width, and depth of the box rather than relying on external box dimensions.

Insert Configuration

Specify the number of cavities, preferred product arrangement, required clearance, finger notches, and additional accessory compartments.

Insert samples should be tested with physical products before bulk manufacturing.

For fragile glass products, the finished packaging should also be evaluated under the intended shipping and handling conditions.

4. OEM & Private Label Customization

Different packaging projects require different materials and structures.

Customization may include:

• Individual or multi-product cavity layouts
• Custom-sized EVA or cardboard inserts
• Product-specific cutout shapes
• Foam color selection
• Printed paperboard branding
• Removable or fixed insert construction
• Finger-access notches
• Layered foam configurations
• Separate compartments for accessories
• Matching branded rigid boxes or folding cartons

EVA foam and paperboard inserts can also be combined in one packaging project when additional product support or visual presentation is required.

5. Packaging Applications
