Damage to fragile cargo during mainline transportation leads to direct financial losses for the transport company and delivery delays. Vibration of the body, friction of pallets and temperature fluctuations destroy the presentation of unprotected products.
Properly selected packaging material completely neutralizes shock loads and rigidly fixes the boxes on a wooden pallet. An integrated approach to packaging protects the cardboard from getting wet when loading in the rain and prevents unauthorized opening of the container.
Corrugated cardboard and bubble wrap
Three-layer corrugated cardboard with a C profile dampens vertical impacts when stacking boxes in a truck. The wave-shaped inner layer distributes pressure over the entire area of the sheet, preventing the cardboard from crumpling under the weight of the upper tiers. Five-layer sheets are used for transportation of heavy household appliances and automobile spare parts.
Shock-absorbing materials are used to protect glass facades and electronics.:
- bubble wrap with a density of 75 to 150 grams per square meter;
- foamed polyethylene 2 mm thick for wrapping polished furniture;
- kraft paper for filling voids inside bulk cargoes.
The bubble wrap forms an air cushion that absorbs pinpoint impacts from the sharp corners of neighboring boxes. The extrusion of high-pressure polyethylene ensures the tensile strength of the bubbles even when the load is strongly compressed by slings.
Foamed polyethylene does not leave micro scratches on the glossy surfaces of televisions and kitchen facades. The closed cellular structure of this material repels water, protecting electronic components from condensation during temperature fluctuations in an unheated trailer.
Stretch film and polypropylene tape
A 20 micron thick hand-held stretch film pulls disparate boxes together into a single monolithic block on a europallet. The high adhesion of the layers allows the film to adhere to itself without using adhesive tape, forming an airtight cocoon around the product.
The technical parameters of the tightening materials include:
- the machine film prestretch ratio is up to 250 percent of the original length;
- breaking load of polypropylene tape from 100 to 300 kg;
- the use of metal clips for rigid fixation of the ends of the tape.
Polypropylene strapping tape cuts into cardboard under strong tension with a manual tensioner. Special plastic corners are used to protect the edges, which distribute the pressure of the tape and preserve the geometry of the package with a rigid screed.
Machine stretch is used on automatic pallet wrappers in large logistics centers. The film's ability to stretch triples the material consumption and ensures maximum load retention when the truck is braking hard.
Filling voids and protecting corners
Moving small parts inside a spacious box inevitably leads to chipped plastic elements. Styrofoam granules are poured into the container, filling all the voids and rigidly fixing the object in the center of the box. The foam filler does not make the parcel heavier, while maintaining air delivery rates.
Protective cardboard corners with a thickness of 5 mm are installed along the vertical sides of the pallet before wrapping with a stretch. The pressed cardboard takes on the impacts of the forklift forks and prevents the stack from piling up when making sharp turns on the highway.
A rigid wooden crate is fastened with nails on top of the main packaging for transporting motor vehicles or industrial equipment. The timber frame transfers the load from the fragile goods to its own structure, allowing heavy pallets to be placed on top without the risk of crushing.
