Isopropanol packaging should always be compatible with the substance being carried indside and Isopropanol packaging is often of plastic, glass or metal. The containers can be in the form of single or combination packaging. Single receptacles would generally be plastic containers up to IBC size or metal drums whereas combination packaging would be a glass or plastic bottle contained in a fibreboard carton.
Whatever type of packaging is used for IPA, it should be capable of containing the substance without leakage or loss to the environment. Closures must be compatible with container and seal correctly when fastened. If bottom outlets are positioned on metal containers such as drums, these should be tightened correctly to avoid leakage. Ideally torque settings for the closures should be used as specified on certification supplied with packaging.
Outer cartons have to be in suitable condition to protect the inner receptacle of combination packages. They need to be fastened with the correct tape strong enought to hold the carton together during transport and handling. Any retaining medium of the inner packaging must be sufficient to separate inner receptacles and prevent damage or excessive movement. It should also be capable of absorbing loss of contents during any breakages.
Whatever packaging is used, it must always be stored in a suitable, stable position in an upright manner, arrows will indicate the correct orientation. To allow for expansion of contained liquid, it is important to leave suficient 'ullage' when filling containers; this information is generally supplied on any certification.
Dependent upon the size of receptacles, IPA may require UN approved packaging. This is determined by transport rules regarding Limited Quantities. When these limits are exceeded which, for IPA, is a 3 litres limit, then the inner receptacle must show UN markings. These markings will include the following:-
- The United Nations Packaging Symbol.
- The packaging's Designated Code.
- A letter designating the Packing Group (s) for the design type and the relative density to which the design type has been tested.
- Either the letter 'S' denoting Solids or inner packaging, or the hydraulic test pressure for liquids.
- The last two digits of the year of manufacture. plastic jerricans and drums also need to show the month of manufacture.
- The State authorizing the allocating of the mark.
- The name of the manufacturer.
UN markings on packaging used for Isopropanol must be on the outer most surface and clearly visible. With combination packages, this will be on the carton and stand-alone containers will have it marked directly onto the containers.
A typical example of a combination package for IPA is 4 x 2.5 litre glass bottles contained in a fibreboard carton. Inner retaining medium can be a moulded pulp design comprising of a base and top or some form of particule medium such as vermiculite or foam chips. Stand-alone containers would typically be plastic herricans of varying capacity or metal drums.
All packaging containing IPA must be correctly labelled with product information according to applicable legislation. This will include hazard information on labels, manufacturer or supplier details, pack sizes and trade names. In addition to this, the outermost surfaces must be marked with transport markings including UN numbers of the goods and hazard diamonds. For transport purposes, IPA is Class 3 and requires a Flammable diamond.
IPA should not be contained in any packaging which shows signs of damage or deterioration.
