Choose paper packaging inserts when a paper-based presentation, flat shipping and easy print customization matter. Choose plastic trays when the product needs a precise molded cavity, visibility or resistance to moisture. Protection tests and local recovery options matter more than a simple “paper good, plastic bad” rule.
The insert should be designed before the outside box artwork because it controls the internal size, product position and assembly steps.
Paper vs plastic packaging insert comparison
| Decision point | Paper insert | Plastic tray |
|---|---|---|
| Product fit | Die-cut folds, tabs and layers | Precise thermoformed cavity |
| Best uses | Cosmetics, cards, gift sets and light products | Bottles, components and products needing exact cavities |
| Appearance | Can match the printed box | Can be clear, colored or hidden |
| Shipping before packing | Often ships flat | Usually nests but still takes volume |
| Tooling | Cutting tool and folding design | Mold or forming tool may be needed |
| Moisture resistance | Limited unless coated | Generally stronger |
| End-of-life | Depends on paper, coatings and local collection | Depends on resin, color, labels and local collection |
| Main risk | Tabs bend or fail under heavy products | Tray cracks, scuffs or conflicts with plastic-reduction goals |
When paper inserts make sense
Paperboard inserts work well when the product is light to medium weight and the brand wants the insert to match a folding carton, mailer or gift box. They can carry printed instructions, color blocks and product labels.
Corrugated paper inserts add thickness for ecommerce kits. Wrapped paperboard inserts can create a more finished presentation in rigid boxes. Browse custom paper insert options when you already know the product layout.
When a plastic tray may be more practical
A plastic tray may be practical when the product needs a repeatable molded cavity, a clear presentation, moisture resistance or fast loading on a packing line. The supplier still needs the real product or an accurate sample to check fit.
For glass, electronics, heavy jars and fragile premium products, protection can matter more than keeping every packaging component in one material family. Compare the tray with molded pulp, corrugated board or another tested alternative rather than changing material without a fit test.
Compare sustainability claims carefully
The US EPA sustainable packaging guidance emphasizes material efficiency and recovery, not one universal material winner. The FTC Green Guides also require environmental claims such as “recyclable” to be qualified when access or conditions are limited.
Ask these practical questions:
- Can the insert be separated from the outer box?
- Are coatings, labels or mixed materials attached?
- Is the material collected where the package will be sold?
- Does the paper option require extra material to provide the same protection?
- Can the insert be made smaller or eliminated after a transit test?
Plan inserts before artwork
The insert affects internal dimensions. If you approve outside artwork first and change the insert later, the box size, panel layout and shipping carton may also change.
Send product size, weight, fragile points, required orientation, order quantity and shipping route before the insert is sampled. For glass or ecommerce delivery, include a drop or transit test plan.

FAQ
Are paper inserts better than plastic trays?
Not in every project. Paper is often better for a paper-based presentation and flat shipping; plastic can be better for a precise cavity or moisture resistance.
Can paper inserts protect glass bottles?
They can, but the board strength, product weight, clearances and shipping route must be tested. Heavy glass may need corrugated, molded pulp or another stronger structure.
Are paper packaging inserts recyclable?
They may be where the material is collected, but coatings, adhesives and attached mixed materials can change the answer. Check the final construction and destination market.
Do plastic trays require tooling?
Thermoformed trays usually require a forming tool. Tooling, material thickness and cavity detail should be included when comparing quotes.
When should the packaging insert be designed?
Design and test it before final box artwork. The approved insert determines the internal dimensions and can change the outer box size.
