  • Wax-Impregnated Waterproof Cardboard Box
    Wax-Impregnated Waterproof Cardboard Box

    When producing wax-impregnated waterproof cardboard boxes, Yilida employs a deep-penetration waxing process using microcrystalline wax. Molten wax penetrates deep into the cardboard, and after impregnation, the cardboard cools and solidifies, forming a uniform coating that provides waterproofing. This is a true molecular-level hydrophobic layer that not only blocks liquid water but also prevents water vapor from seeping back into the cardboard. After applying such a wax layer, the cardboard boxes can still maintain their flexibility and strength, and will not break easily or be unable to withstand heavy pressure like ordinary cardboard boxes.


    Product Applications

    Wax-impregnated waterproof cardboard boxes are mainly used in fresh food and cold chain transportation, for long-distance sea freight, you can also choose this type of box. During transportation, if the temperature is low, ordinary cardboard boxes will become brittle when placed at -15°C, and will no longer be able to provide effective loading and protection. However, our waxed cardboard boxes can still maintain their normal state after being frozen at -40°C. By this comparison you can see it has a significant advantage.

    Furthermore, all materials used by Yilida are food-grade and can come into direct contact with various products such as fruits, vegetables, meat, and seafood, meeting relevant international safety standards.


    Customization Service

    As a direct supplier, we have a complete production line to handle your order needs. Please contact us to send us the customized dimensions and the designs you wish to print. There's not much to explain about the size; just customize it according to your actual packaging needs, or contact us for advice. The pattern printing uses UV digital printing technology, resulting in clear printing and excellent effects.


  • Angle Boards
    Angle Boards

    At Yilida's six angle boards production lines, you can find various types of paper corner protectors, including L-shaped, U-shaped, and round ones. 20 years of production experience has given us advanced technology and production capabilities, ensuring our products meet standard moisture content requirements and are ISO9001 certified, certified by PONY Testing, and FSC certified (100% recycled and MIX100%).


    What are Paper Corner Protectors?

    Paper corner protectors, also known as angle boards, edge boards, corner strips, or corner wraps, are made from multiple layers of high-strength kraft paper using a precision composite process. They are used to wrap the edges and corners of products, providing protection, reinforcement, and support. Compared to wooden or plastic corner protectors, they are lighter, recyclable, and more convenient to use.


    What are Different Types of Paper Corner Protectors Suitable for Packaging?

    Yilida can customize paper corner protector sizes to meet your packaging needs. As for shapes, the main types include L-shaped, U-shaped, round, solid, and flat, but V-shaped can also be customized.

    L-shaped corner protectors can be placed on the edges of cardboard boxes or the corners of items needing reinforcement to prevent the boxes from being crushed or deformed, or the items from being damaged by impact.

    U-shaped corner protectors can also protect corners; they can be directly clipped onto corners and are especially suitable for protecting doors, windows, glass panels, tiles, and furniture. They are very convenient to use and act as a cushioning barrier, making the items they protect safer during transportation.

    Round, solid paper corner protectors, also known as wrap-around ones, are definitely a better choice if you're packaging and protecting cylindrical items compared to other types. They are ideal for packaging items with rounded shapes such as shipping drums, cans, and rolls, providing strong cushioning and preventing the contents from denting.

    Finally, flat paper corner protectors are suitable for packaging furniture, electronic equipment, or glass curtain walls. They can also be used at the bottom of paper pallet legs to increase load-bearing capacity.


  • Slip Sheets
    Slip Sheets

    In addition to waxed waterproof cartons and paper corner protectors, Yilida also offers paper slip sheets. These packaging products from our factory can help you enhance the protection of your goods during transportation and storage while being lightweight, convenient, and recyclable.


    Why Use Paper Slip Pallets?

    The biggest advantage is that paper slip pallets improve the efficiency of handling and loading/unloading operations. Their small size and light weight save transport space and don't add much weight to goods. Moreover, despite their lightness, a single paper slip pallet can still bear a load of 1 ton or even 1.5 tons or more, with even higher static load-bearing capacity, making them a viable alternative to plastic and wooden pallets. Wooden pallets require fumigation, which is troublesome, and plastic is not as environmentally friendly as paper.

    Furthermore, paper slip pallets are lighter than wooden pallets, reducing fuel consumption, which means lower transportation costs, and saving on the purchase, repair, and return costs of wooden pallets.


    Use and Storage

    Using paper slip pallets requires a forklift equipped with a push-pull mechanism. The size, thickness, and number of lips can be customized to meet different loading and unloading needs. Unused paper pallets should be stored in a dry, cool environment and kept flat to prevent them from bending or deforming. For long-term storage, it is recommended to avoid direct sunlight or extreme temperatures.
