Shanghai Hongying Industrial Co., Ltd. (上海弘郢实业有限公司) is an EPE pearl cotton packaging factory in China. We manufacture EPE foam sheets, rolls, pads, slotted inserts, shaped liners, edge protectors and corner guards for factory packaging, export cartons and custom protective packaging orders. EPE foam thickness affects cushioning, product fit, carton space and cost, so we choose the structure around your real product instead of selling one fixed size to every buyer.

What our factory can make
For thickness-related enquiries, our factory can cut EPE foam by sheet size, laminate layers, open slots, shape compartments and make protective pads that match your product and carton. Customers can send product photos, dimensions, weight, quantity and packaging purpose; we then recommend a thickness and structure for sample confirmation.
- Cut-to-size EPE foam sheets for separators, liners and cushioning pads.
- Custom slotted EPE foam inserts for products that need fixed positioning.
- Layered EPE foam pads for products that need stronger cushioning.
- EPE foam corner guards and edge protectors for carton and product edge protection.
- White, black and pink anti-static EPE foam options depending on the order.
Start with the product, not the foam number
A light cosmetic box, a ceramic bowl and an electronic training kit do not need the same EPE foam structure. The first step is to understand where damage is likely to happen: surface scratches, corner impact, vibration, compression, product movement or carton collapse. Once the risk is clear, the supplier can discuss thickness, density, layers and slot depth.
For simple surface separation, buyers may only need thin EPE foam sheets. For products that must stay fixed in a carton, a thicker custom EPE foam insert or a layered insert is usually more useful. For heavy or sharp products, thickness should be reviewed together with support points and carton strength.
- Use thinner sheets for scratch protection and product separators.
- Use thicker pads when the product needs more impact absorption.
- Use slotted custom inserts when positioning is as important as cushioning.
- Use corner guards when edge damage is the main shipping risk.
Common thickness decisions in factory packaging
For EPE foam sheets, the buyer usually confirms length, width, thickness and quantity. For a custom insert, thickness must be checked with the cutout size because the slot must hold the product without making removal difficult. If the insert is too thin, the product may move. If it is too thick, carton size and material cost may increase unnecessarily.
When the product has uneven shapes, raised buttons, glass edges or delicate coating, a sample is valuable. A sample helps confirm whether the foam touches the right areas, whether the product can be removed easily, and whether the carton still closes cleanly after the insert is loaded.
| Packaging goal | Typical direction |
|---|---|
| Scratch protection | Cut-to-size EPE foam sheet or thin liner |
| Shock absorption | Thicker pad, layered sheet or structured insert |
| Stable positioning | Custom slotted EPE foam insert |
| Carton edge protection | EPE foam corner guard or edge protector |
Information to send for a faster quotation
A good quotation request should include product photos, dimensions, weight, quantity, packaging goal and destination market. If the buyer already has a carton size, inner box size or current damaged packaging photos, those details can reduce guessing and speed up sampling.
Shanghai Hongying Industrial Co., Ltd. (上海弘郢实业有限公司) can discuss EPE foam sheets, rolls, custom inserts, anti-static options, black foam and edge protection based on the buyer project. The goal is to balance protection and cost rather than use the thickest material by default.

FAQ
Is thicker EPE foam always better?
No. Thicker foam may improve cushioning in some cases, but it can also increase carton size and cost. The right choice depends on product risk and packaging structure.
Can one product use more than one thickness?
Yes. Many custom EPE foam inserts use layers or different support areas so the product is protected without wasting material.
Do I need a sample before ordering?
For custom inserts, fragile products or export packaging, sample confirmation is strongly recommended before bulk production.
