How to customize the inserts to fit your product

We can ensure that you have the most appropriate lining solution for your product that will both protect it and enhance the customer experience.

Product analysis:

First of all, we will conduct a comprehensive analysis of your product, including size, weight, shape, fragility and whether anti-static or moisture-proof treatment is required.

Material Recommendation

Depending on the characteristics of the product, we will recommend the most appropriate material. For example, foam or pearl cotton may be recommended for fragile products, and bubble wrap may be chosen for products that need to be shockproof.

Size Measurement

We will accurately measure the size of the product and design the size of the liner according to the shape of the product to ensure that the liner fits tightly and reduces shaking during transportation.

Customized design

We will work with you to design the internal structure of the liner, such as grooves, dividers, etc., to ensure that the product is placed stably in the insert.

Sample making

We will make samples of the inner liner, and you can conduct actual tests to verify the protective effect of the liner and the adaptability of the product.

Feedback Adjustment

Based on the feedback from the sample test, we will make necessary adjustments to optimize the liner design.

Mass Production

Once the samples are approved, we will move into mass production to ensure that each batch of liners meets your quality standards.

Quality Control

Throughout the production process, we implement strict quality control measures to ensure that each product achieves the desired protective effect
