Complete Guide to Choosing the Best Packaging Insert for Protection, Presentation, and Performance
Packaging inserts are an essential part of custom packaging box design. A well-designed insert helps secure the product inside the box, reduce movement during storage and transportation, improve product protection, and enhance the overall presentation when the package is opened.
Selecting the correct insert requires balancing several factors:
- Product weight
- Product geometry
- Fragility
- Surface protection requirements
- Retail display requirements
- Sustainability goals
- Production volume
- Manufacturing cost
Because no single insert material is suitable for every application, packaging engineers typically evaluate each option based on protection, appearance, manufacturing efficiency, tooling costs, and environmental performance.
What are the options for custom product packaging inserts?
Common custom packaging insert options include EVA foam inserts, EPE foam inserts, PU foam inserts, cardboard inserts, paperboard inserts, blister trays, molded pulp inserts, velvet-covered foam inserts, satin fabric inserts, and printed paperboard-covered foam inserts.
Foam Inserts for Custom Packaging Boxes
Foam inserts are widely used in protective packaging because they can be die-cut to match the product shape. They provide cushioning, shock absorption, and stable product positioning inside the box. Foam inserts is the top choice for custom luxury rigid boxes.
EVA Foam Inserts
EVA foam is a premium packaging insert material with a compact surface, small pores, high density, and good elasticity. It is ideal for high-value products such as watches, electronic products, tools, hardware components, and luxury gift sets.
EVA foam inserts provide excellent protection while maintaining a clean and professional appearance. Compared with EPE or PU foam, EVA is more expensive, but it is often the preferred choice for products that require both safety and premium presentation.
EPE Foam Inserts
EPE foam, also known as expanded polyethylene foam, is lightweight, anti-static, and offers excellent cushioning performance. It is more affordable than EVA foam and is commonly used as internal protective filler.
Because EPE foam has larger pores and a rougher surface, it is better suited for cushioning and transportation protection than luxury product display.
PU Foam Inserts （Sponge)
PU foam, commonly known as sponge, is soft, breathable, resilient, and widely used in packaging. Standard-density PU foam is a cost-effective option for gift boxes, glassware, electronic accessories, tools, and other products that require soft cushioning.
Velvet-Covered Foam Inserts
Foam inserts can be covered with velvet to create a more refined and premium appearance. Velvet-covered foam inserts are commonly used for jewelry boxes, watch boxes, awards, collectibles, premium gift boxes, and luxury packaging.
The soft velvet surface helps improve the visual effect of the packaging while protecting the product from scratches.
Printed Paperboard-Covered Foam Inserts
Foam inserts can also be covered with printed paperboard to match the outer packaging design. This option combines the cushioning performance of foam with a clean, branded surface.
Printed paperboard-covered foam inserts are suitable for cosmetic gift sets, electronics packaging, promotional packaging, and retail product boxes that require both product protection and consistent brand presentation.
Blister Inserts for Custom Packaging Boxes
Blister inserts are molded plastic trays designed according to the product shape. They provide accurate product positioning, a neat display effect, and consistent structure for mass production.
Blister inserts are commonly used for cosmetics, glassware, electronics, accessories, toys, tools, and retail packaging.
PET Blister Inserts
PET blister inserts offer high transparency and excellent product visibility. PET is often preferred for packaging exported to Europe and North America because it provides a clean display effect and better environmental performance compared with some other plastic materials.
PET blister trays are suitable for cosmetics, skincare products, retail goods, electronics, and product sets that need a clear and professional presentation.
PVC Blister Inserts
PVC blister inserts have strong formability and can be produced in transparent, colored, or frosted finishes. They are flexible for different product shapes and display requirements.
However, PVC is less environmentally friendly than PET, so it may not be the best choice for brands with strict sustainability requirements.
PS Blister Inserts
PS blister are available in standard black/white PS and flocked velvet PS. standard PS is a simple and cost-effective product-holding solution, while flocked velvet PS creates a more premium appearance.
The flocked velvet surface helps reduce friction and prevent scratches, making it especially suitable for cosmetics, glass bottles, perfume packaging, and premium gift boxes. Standard colors are usually black and white, while custom colors often require a higher minimum order quantity.
Cardboard and Paperboard Inserts
Cardboard inserts and paperboard inserts are practical, cost-effective solutions for products with simple shapes. They can be die-cut, folded, printed, and color-matched to the overall packaging design.
Compared with blister inserts, cardboard and paperboard inserts do not require mold fees, making them more flexible for small and medium-sized orders. They are widely used for cosmetics, candles, food products, small bottles, stationery, gift sets, and retail packaging.
For brands looking for a recyclable and budget-friendly packaging insert, cardboard and paperboard inserts are often a practical choice.
Molded Pulp Inserts for Custom Packaging Boxes
Molded pulp inserts are made from paper-based pulp materials and are a popular eco-friendly packaging insert option. They provide stable product support, good cushioning, and a natural appearance.
Molded pulp inserts are suitable for electronics, cosmetics, wine bottles, candles, glassware, food packaging, and sustainable gift boxes. They are often chosen by brands looking for recyclable, plastic-free, or environmentally friendly packaging solutions.
Compared with plastic blister, molded pulp offer a more natural look and better sustainability positioning. They are especially suitable for brands that want to reduce plastic use in packaging. Of course, the price is also higher.
Satin Fabric Inserts for Custom Packaging Boxes
Satin fabric inserts are commonly used in luxury packaging boxes. The satin surface creates a soft, elegant, and refined display effect, while the inner foam, or cardboard structure supports the product.
Satin fabric inserts are suitable for jewelry boxes, watch boxes, perfume boxes, awards, collectibles, and premium gift packaging. They are often used when product presentation is just as important as protection.
Shredded Paper Protective Fill
Shredded paper is a soft, recyclable cushioning material placed inside boxes to protect products. It effectively absorbs shock, prevents movement during transit, and is widely used in gift packaging.

FAQs About Custom Packaging Inserts
How can you ensure my product won’t be damaged during shipping when custom packaging boxes ?
We design custom packaging inserts based on your product’s size, weight, and structure. Before mass production, we assemble the product with the packaging and perform drop tests to verify its protective performance. Production begins only after the packaging successfully passes our quality and transportation tests.
My product is large and heavy. How can the inserts provide protection while controlling costs?
For large or heavy products, using solid EVA foam can significantly increase costs. A more economical solution is to combine a cardboard structural support with precision-cut EVA foam in critical protection areas. This hybrid design delivers excellent protection while reducing material costs. Contact our packaging specialist for a customized insert solution.
Can foam inserts be made in custom colors?
Yes. Foam inserts can be manufactured in custom colors, but custom color production typically requires a higher minimum order quantity. Black and white are the standard colors available for most projects.
Which packaging insert is the most cost-effective?
The most economical insert depends on your product, production volume, and packaging requirements. For products with simple shapes and lower production quantities, cardboard inserts are usually the most cost-effective because they require no mold tooling. For medium- and high-volume production, thermoformed blister inserts often provide the best balance of cost, precision, and production efficiency.
Which insert is best for luxury packaging?
Rigid boxes combined with EVA foam or velvet‑covered sponge inserts offer an excellent choice for luxury packaging. Meanwhile, molded pulp—eco‑friendly, clean, and sustainable—has also become a popular option among many brands today.
What insert is best for glass bottles?
For optimal glass bottle protection packaging, foam inserts are the preferred solution. EVA foam offers superior cushioning and a premium aesthetic, while EPE foam provides a cost‑effective alternative with adequate shock absorption for less demanding applications.
Best inserts for cosmetic packaging?
For cosmetic packaging, blister inserts are the most commonly used solution. They offer a clean appearance while providing a precise fit for tubes, bottles, and other container shapes.
