Shock-absorbing inner and outer packaging designs for transport packaging continued

Packaging

Original manufacturer packaging

According to the design, the original manufacturer's packaging is generally used for pallet shipments, not single shipments; and this type of packaging is suitable for one-time shipment of products, not multiple shipments. Therefore, reusing the original manufacturer's packaging for parcel delivery network delivery products will increase the risk of product damage. Only when the manufacturer's packaging is professionally designed to withstand vibration and is in a relatively new state can it be used again.

Double box packaging

If you use the original manufacturer packaging, you can use double box packaging. All electronic devices require double box packaging. When packaging, make sure that the original packaging is in good condition and that the internal foam packaging is free of cracks or cracks. Use a new corrugated box with an aspect ratio of at least 15 cm larger than the original manufacturer's packaging for external packaging. Fill the bottom of the new cartons with at least 7 cm of cushioning material, such as loose-filled expanded polystyrene granules or other suitable materials, without using crumpled or shredded paper. Place the original manufacturer packing box on the upper part of the cushioning material and in the middle of the new cartons to ensure that at least 7 cm of buffer layer is formed on the five sides of the package. Then, fill the remaining space in the package with cushioning material.

Lining bags

When sending books, floppy disks, and video recordings, protective bags are recommended. The liner packing bags are generally selected to use recycled paper fibers as a protective layer and heavy kraft paper as an outer layer. If you need to use a stronger bag, it is recommended to use a lightweight bag with a foamed membrane as an internal cushion to cushion the vibration.

To ensure the security and confidentiality of consignments, it is equally important that the bags are properly sealed and properly cushioned. A good seal can increase the strength of the box. In order to ensure the safe sealing of the packaging box, it is recommended not to use masking tapes, cellophane tapes, duct tapes, ropes or paper packaging. Strong polypropylene or PVC “case seal” tapes with a width of not less than 5 cm should be used.

New buffer packaging

The famous computer manufacturer IBM has successfully used cushioning materials to package printers. It also has the advantages of cost savings and environmental protection. With the development of the IBM 4772 new bank printer, the company urgently needed a newer packaging system. Prior to the same specifications, the packaging used by the printers used foam cushions and corrugated components to form a bulky, loose packaging that provided insufficient shock protection during transportation. IBM Packaging Engineers wanted an environmentally friendly approach with the goal of abandoning the use of hybrid packaging (foam and corrugated packaging) to provide a more consistent and uniform protection for the product, using easily recycled materials, and reducing overall processing costs.

For this reason, IBM chose a product called Corrupads. The product is a corrugated liner made from 100% waste paper. Multi-layered materials absorb impact forces and minimize the resilience normally present in resilient foam materials, thereby reducing the degree of vibration experienced by the printer during storage and transportation.

In IBM's packaging product testing, this new gasket surpassed the IBM test specification. The average weight of the printer is 32 pounds, requiring a drop test from the 30-inch drop height to the 8 sides (1 key angle, 1 key edge). At the same time, each axis of the product also undergoes 2-200Hz sinusoidal sweep vibration to determine the resonance point. Then, each resonance point stays in the three axes for 15 minutes each. Finally, the packaged products each received a high degree of safety random vibration of 1.04 G rms in three axes. After these tests, it was proved that the function and appearance of the product meet the requirements.

With Corrupads products, molds necessary for the production of expanded polystyrene parts are no longer needed, so the cost can be directly reduced by more than $20,000. Smaller packaging produces the same cushioning effect as polystyrene or polyethylene foam, so the overall package size can be reduced. This also reduces shipping costs by 10%, reduces storage space by 25%, and maximizes pallet load.

In addition, since the outer corrugated box (carton) has a small volume, corrugated material can be saved. As the packaging shrinks, more packages can be loaded on the trays, reducing the use of pallets by up to 25%. At the same time, Corrupads products open up the market for post-print paper.

While large products require solid packaging, the protection needs of small products cannot be ignored, especially for mailed products. To this end, Pactiv launched the Armor-Lite® parcel. In terms of structure, a layer of air cushion is pressed between the outer polyethylene layer and the inner layer. The air cushion consists of a 3/16 inch polyethylene film inner layer sandwiched between a white outer layer/silver polyethylene film inner layer. With this combination, a clean external surface is provided, and the inner layer also enhances opacity.

The Armor-Lite® mailer comes with multiple release liners that are sealed with a self-adhesive adhesive for easy closure. In addition, thanks to its all-plastic structure, postal parcels can withstand a variety of climatic conditions. The Armor-Lite® mailer has higher tear strength and superior puncture resistance and moisture resistance compared to a standard kraft/cushioned mailer.

The Armor-Lite® mailer can also be printed or custom-made in up to 6 colors, with a decorative effect and is particularly suitable for use as a gift parcel or promotional tool.

Corrugated paper and foam film can be used as the protective layer for general products. However, if the product is fragile or needs protection, the packaging material is required to have a high cushioning effect and a fixed position function. Sealed Air's Instapack® foaming system is specifically designed for this requirement. It features fast, easy, and versatile packaging features that make it easy to produce protective polyurethane foam packaging online. Whether it requires high-precision padding or high-speed vacuum filling, or heavy-duty barriers or supports, Instapack® systems are suitable.

Instapack® foams according to the shape of the product, firmly wrapping the product

Instapack® foam expands 280 times in liquid state, so vehicle packaging materials can be stored in two 210 litre buckets. What's more, Instapack® foam can be freely foamed at any time, anywhere and as required by the customer.

The foaming and packaging process of Instapack® is simple. In the case of foaming on site, the foam is first injected into a cardboard box lined with Sealed Air's high-strength Instamate® film, and the film is folded so that the product can be placed on the raised foam; The second layer of Instamate® film is placed on top of the product and then infused with more Instapack® foam.

For pre-molding, a simple wooden mold can be used to make the desired gasket shape; Instamate® film is placed in the mold and Instapack® foam is injected. The product is as perfect as it is packed in a preformed pad.
