Tampering with date stamps, no easy solutionFollowing the recent story online about the ease with which date stamps can be removed from food items, Rowan Beattie, MD of Pyrotec comments on the problems offered by solvent-based inks. Pyrotec PackMark is a division of the brand that supplies factory-level coding equipment used to print date codes. It is the exclusive South African distributor of the international Markem-Imaje range of coding equipment. "Unfortunately there is no hard and fast solution," he says. "Any ink that is solvent-based will be able to be removed by a solvent. Unfortunately, even if a permanent ink were to exist, the retailer would still be able to apply another label over it if thus inclined. "There are other coding alternatives available - some more resistant than others - but each will have its advantages and disadvantages. It is about determining what will work best for you and your product." The good news is that reputable manufacturers of perishable goods are prudent about printing correct and legible date codes on every product they ship out of their factories as they aware of the damage a negative consumer experience could cause. "The company works closely with these manufacturers to ensure that they have access to the most advanced technologies available to ensure that they deliver a top-quality product." Coding technologiesThere are a number of core coding technologies currently available worldwide, which can be simplistically categorised as follows:
"There is constant innovation and development in the market as we seek to find the consummate solution. As brand owners, we need to be aware of the alternatives available and determine which technologies will best suit our products. It is vital that we keep abreast of advances in technology so as to be able to educate ourselves and ultimately the consumer," advises Beattie. "However, it is equally important that we, as consumers, ensure that we are adequately informed. If we find that there is no 'best before' date on the perishable product, or that the goods have expired, we need to report the matter to the Consumer Goods Council of South Africa (CGCSA) for investigation. Not only should consumers insist on being informed with regards to a product's origin, traceability, composition and quality - it is now a legal requirement that this information is made readily available," he concludes. |
