Bubble Film vs. Kraft Paper: Rigging and Product Protection
Bubble and kraft paper are packaging used to wrap an object in a shipping carton or moving carton. However, their field of action is different: the bubble film is used to protect the object from knocks and shocks while the kraft paper is used to stall the object and prevent it from moving. Their goal is common: to prevent the object from being damaged during transport.
The bubble film, the protective mattress of your fragile objects
Bubble wrap is a plastic film covered with thousands of air bubbles. It is these air bubbles that form a protective mattress for the wrapped object. Thus, the object is protected thanks to the air bubbles that form a protective barrier capable of reducing the impact of a shock or a blow . The bubble film is also antistatic , which reduces the number of discharges of an object sensitive to static electricity.
The size of the bubbles vary according to the object to protect : the default size is 1 cm in diameter but there may be bubbles of 2.5 cm in diameter! Bubble wrap with 2.5 cm bubbles are designed to hold only large objects. It is therefore better to use bubble film with 1 cm bubbles for fragile objects of small size.
You can find the bubble film in different formats including:
the roll of 10 m, 50 m or 100 m long bubble wrap that allows you to cut exactly the desired bubble wrap;
the dispenser bubble precut film sheets 30 x 30 cm, suitable for packaging small items;
the protective cover for sofas (bubble film + foam film), perfect to protect your sofa during a move.
Kraft paper, the perfect packaging
The main use of kraft paper is the storing of objects in a carton but it can also be used as food packaging. Kraft paper is known for its strength (in German “kraft” means “strength”), for its versatility and for its ecological aspect (it is created from wood from sustainably managed forests and is 100% recyclable).
Thanks to its great resistance, it does not tear at the slightest blow and can thus effectively protect the object by keeping it in place in the box . The strength of kraft paper is verified by the basis weight (ie the mass of kraft paper per unit area, expressed in g / m²), the breaking strength (ie ie the maximum length of the paper that does not break) and the tear strength (ie the maximum force that can be applied to the craft paper before it tears).
Kraft paper exists in different formats to meet the needs of all:
the roll of 50 cm, 1 m even 1.20 m, practical to cut the strip of paper kraft which one needs;
the spiral kraft paper dispenser box , ideal for stalling an object in a cardboard box quickly;
kraft paper is also declined in envelopes , it is used in particular on the outer face of the bubble envelope, and may be associated with the bubble film to create an opaque protective film .
Conclusion: additional packaging
The bubble film and the kraft paper are not packagings to oppose but to combine to obtain an optimal protection of your objects to transport. Thus, by wrapping your fragile bubble film objects and stowing them in the cardboard with craft paper, you are sure that nothing will happen to them during their transportation.
