Transportation of large household appliances are always fraught with risks, and the question of what refrigerators are packed in at the factory and how they are protected when moving worries many owners. Factory packaging is a complex engineering complex, developed over years of testing to protect the case and internal units from vibrations, shocks and moisture. Understanding the structure of this “layer cake” of materials is necessary not only for receiving goods in the store, but also for organizing a competent move.
Many mistakenly believe that it is enough to simply wrap the device with tape or an old blanket, however modern models they require a more delicate approach due to the use of thin metal alloys in doors and sensitive electronic control boards. Improper fixation of the compressor or lack of corner cushioning can lead to depressurization of the freon system even before the first start-up. Therefore, studying the types of packaging becomes a matter of financial security for the buyer.
Structure of factory packaging: multi-layer protection
On the production line, each refrigerator passes through a conveyor, where a primary protective layer is put on it. Most often this polyethylene sleeve or shrink film that fits tightly around the body. This material prevents micro-scratches on the paintwork during movement along the assembly line and protects the metal from oxidation during storage in a warehouse. The film also acts as a barrier against dust that could get stuck in the ventilation holes.
The next level of protection is the corner elements. Corner shock absorbers made of polyethylene foam or polystyrene foam they take the brunt of the impact when the box falls on a corner, which is the most common accident scenario during loading. They firmly fix the equipment inside the cardboard box, preventing it from moving. Without these elements, even a slight poke during loading could lead to a dent on the door or a chip on the side wall.
The external protection contour is corrugated cardboard high density. It performs several functions: protects from mechanical damage, moisture and sunlight. A cardboard box is often impregnated to increase its tensile strength. Inside the box there may be additional cardboard spacers that hold shelves, drawers and fasteners, preventing them from dangling inside the chamber during shaking.
Basic materials: foam, cardboard and films
Understanding what is being packaged refrigerators, one cannot fail to mention the physical properties of the materials used. Expanded polystyrene (foam plastic) is a classic of the genre. It is light, cheap and has excellent shock-absorbing properties. However, it has a significant disadvantage: it crumbles under strong compression and can become electrified, attracting dust. In expensive models, it is often replaced with a more environmentally friendly and durable foamed polyethylenethat bends without breaking and better absorbs high-frequency vibrations.
Cardboard is used not only as outer shell, but also as an internal stabilizer. Multilayer corrugated cardboard able to withstand significant compressive loads, which allows equipment to be stacked in warehouses. It is important that the cardboard is dry: wet material loses up to 80% of its strength and ceases to protect the device. That is why storing refrigerators in the open air is strictly prohibited.
Stretch films and adhesive tapes used for fixation deserve special attention. Polymer tapes ensure the tightness of the packaging, preventing moisture from getting inside the box. When packing for a move yourself, bubble wrap is often used. It is effective for protection against scratches, but does not cope well with pinpoint impacts, so it must be combined with rigid elements such as sheets of foam plastic or thick cardboard.
Fixation of internal components during transportation
The packaging protects not only the outer shell, but also the “filling” of the refrigerator. The most critical element is compressor. In modern models, it is suspended on springs inside the housing, and if shaken, it can damage pipelines. To prevent this, the manufacturer uses special shipping bolts or rigid foam inserts that block the movement of the motor relative to the frame.
The internal space of the chamber is also subject to fixation. Glass shelves and plastic drawers should not move freely. They are secured with cardboard spacers or fixed with tape (in the factory, special adhesives are used that do not leave marks). If you transport the refrigerator yourself, be sure to remove all removable elements or securely fix them, otherwise glass breakage is almost guaranteed.
Refrigerator doors are another risk area. The hinges may not withstand the weight of a heavy door when jerked if it is not fixed. Transport tape or special belts tightly press the door to the body, preventing it from swinging open. This also prevents deformation of the sealing rubber, which, if constantly opened during shaking, can stretch or twist.

Comparative table of packaging materials
To better understand the differences in protection, consider the comparative characteristics of the main materials used by manufacturers and logistics companies.
| Material | Main function | Pros | Cons |
|---|---|---|---|
| Expanded polystyrene | Shock absorption | Cheap, light | Crumbles, takes up volume |
| Corrugated cardboard | Protection from scratches and moisture | Environmentally friendly, rigidity | Afraid of water, loses strength |
| Stretch film | Fixation of layers | Tightness, elasticity | May leave an adhesive trace |
| Foamed polyethylene | Vibration protection | Strength, does not absorb water | High cost |
As can be seen from the table, the ideal packaging option combines several materials. Combined protection allows you to compensate for the shortcomings of one material with the advantages of another. For example, cardboard holds its shape, and foam plastic absorbs impact energy.
Why can't you use newspapers for packaging?
Newsprint paper contains printing ink, which, when in contact with plastic or metal under conditions of high humidity (for example, during temperature changes), can leave irremovable stains. In addition, paper quickly absorbs moisture and loses strength.
Rules for self-packing for moving
If the original packaging is lost or has become unusable, you have to look for alternatives. Primary preparation starts with defrosting and drying the chamber. You cannot pack a damp refrigerator - this will lead to the formation of mold and corrosion of the internal elements. After drying, all doors must be tightly closed and secured.
Best suited for wrapping the body bubble film with large cells. It needs to be wrapped around the device in 2-3 layers, paying special attention to the corners and protruding parts. The structure is wrapped with stretch film on top to prevent bubbles from bursting. If possible, find sheets of polystyrene foam or penofol and attach them to the side walls before final wrapping.
⚠️ Attention: Never use ordinary stationery tape directly to the paintwork to secure doors. It may leave traces of glue or even damage the paint when peeled off. Use masking tape or apply a layer of paper/film.
When transporting vertically, which is the only correct option for most models, it is important to ensure stability. Tilt more than 40 degrees can lead to oil leakage from the compressor into the refrigerant circuit, which will cause breakdown at the first start. Therefore, in the back of a truck or inside a car, the refrigerator must stand strictly vertically and be securely wedged.
Environmental aspects and recycling of packaging
The issue of recycling packaging is becoming increasingly relevant. Cardboard and paper they are waste paper and are subject to mandatory recycling. They can be handed over to special collection points, which will help save the trees. Polystyrene foam (expanded polystyrene) is more difficult to recycle, but there are technologies for its recycling for the production of building materials.
Plastic films and bags can also be recycled if appropriate collection has been established in your city. Incineration of packaging strictly prohibited: when burning synthetic materials release toxic substances that are hazardous to human health and the environment. Properly sorting waste after unpacking your refrigerator is a simple step towards environmental responsibility.
Some manufacturers are switching to biodegradable materials. Packaging made from recycled cardboard or craft paper is becoming the standard for premium brands. It looks more aesthetically pleasing and is easier to dispose of at home, for example, in compost pits (in the absence of a varnish coating).
What to do with large volumes of polystyrene foam?
Foam takes up a lot of space in trash cans. It can be crushed (it is highly electrified, so it is better to do this with gloves and lightly sprinkle with water) and take it to special polymer collection points, if there are any in your region.
Frequently asked questions (FAQ)
Is it possible to transport a refrigerator lying down?
Extremely not recommended. When transported horizontally, oil from the compressor may leak into the cooling system, and the compressor itself may become loose due to vibration. If there is no other way out, you need to lay it only on the back wall (radiator fins) or on the side indicated in the instructions, and let it stand upright before turning it on for 4 to 24 hours.
Do you need to keep the original packaging after purchase?
There is no point in storing a full box on the balcony - it will freeze the place and may become damp. However, it is recommended that the corner foam pieces and internal bracing be retained. They can be useful when moving or for returning goods to a store in the event of a defect, since the lack of packaging can cause refusal of acceptance.
How to replace polystyrene foam when moving?
As an alternative, you can use old blankets, blankets, foam foil insulation (penofol) or sheets of drywall to create a rigid frame. The main thing is to ensure a tight fit of the shock-absorbing material to the body.
How long can you store the refrigerator in its packaging?
Long-term storage in the original packaging is possible only in a dry room at room temperature. You cannot store a packaged refrigerator outside or in an unheated garage: temperature changes will cause condensation inside the box, which will lead to rust of the case and damage to the electronics.
