Current status (at January 2010)

Published by CEN: 2006

Published by BSI: 2006

Reviewed: Due for first review 2011

Amended: 2009 to include Annex ZB which confirms that this Standard gives a presumption of conformity to the new Machinery Directive 2006/42/EC as well as 98/37/EC.


The term “wrapping machine” is used to describe a wide range of machines with quite different mechanisms and hazards, so Clause 3 defines the main types of wrapping machine and illustrates their method of operation using isometric drawings. This is so users of the Standard can be sure which type of wrapping machine they are considering and the specific requirements for that machine.

Clause 3 also defines terms commonly used when discussing wrapping machines like shrink wrapping, fin seal, stretch wrapping, thermoplastic film and film compensator.

Injuries caused by wrapping machines

Clause 4 of the Standard identifies the injuries that can be caused by each type of wrapping machine.

The injuries most often caused by wrapping machines are:

Safety principles established by this Standard

Safety by design on reel unwind mechanisms

The Standard recognizes that on most wrapping machines it is possible to design the reel unwind mechanism so that it is safe by design and so does not need to be enclosed within interlocked guards. Various techniques for ensuring safety by design are illustrated in clause

IP rating appropriate for the method of cleaning

Clause includes a Table to help ensure that the degree of protection of electrical enclosures is appropriate for the cleaning method used on the machine. For instance if the machine is cleaned with a damp cloth a rating of IPx4 is appropriate, but if low pressure running water is used the protection rating must be IPx5.

Discharge openings on stretch film wrapping machines

Many stretch film wrapping machines are used in shops where space is limited and it is not always possible to provide the safety distances required by EN ISO 13857. Clause describes a series of methods of providing adequate protection at discharge openings where space is restricted and a simple tunnel guard cannot be used.

Hot melt adhesive systems

Clause 5.4.6 describes the detailed requirements necessary to protect against the burning hazards presented by pressurized and unpressurized hot melt adhesive systems. These requirements include the need for thermal insulation, warning pictograms and guards to prevent overspray of pressurized adhesive.

Power hold

EN 415-5 recognizes that an increasing number of wrapping machine use servo and other electronically controlled drive motors where it may not be possible to disconnect power to these drives during an operator intervention because of the risk of the mechanisms moving relative to each other. Clause describes the precautions that must be taken if a “power hold” system is used including the integrity of control circuits and the need for movement monitoring during the operator intervention.

Protection measures for shrink tunnels

Clause 5.15.3 describes how shrink tunnels for shrink-wrapping machines must be labelled and controlled to minimize the risk of burning. The use of the “danger hot surface” warning pictogram is recommended above the infeed and discharge openings of shrink tunnels.

Special requirements are described for shrink tunnels used for shrink-wrapping aerosol cans to prevent the risk of fire and explosion in the event of the shrink tunnel conveyor stopping with product still inside, e.g. during a power failure.

Effects of the Standard

Although EN 45-5 has only been published for a relatively short time it is noticeable that an increasing number of new wrapping machines and shrink-tunnels are being equipped with the “Danger – hot surface” warning pictograms and “Do not reach in” prohibition pictograms required by the Standard. There is also some evidence that manufacturers have recognised the need to provide tunnels at infeed and discharge openings that provide the required 850mm safety distance to the nearest danger zone.

Purchasing the Standard

EN 415-5 can be purchased as BS EN 415-5: 2006 + A1: 2009 from BSI Standards.
