    The Sandwich-Wrapping Debate - Tin Foil vs Cling Film


    The good-old packed lunch; easy, money-saving and something to enjoy on the go. But what’s the best way to wrap your lovingly-prepared sandwich to keep it fresh to eat at lunchtime? Tin-foil or cling-film?  Aluminium film or plastic film? Whatever you call them, there’s pros and cons for using both.

    So, cling-film is usually made from low-density polyethylene. It’s that tricky-to-use film that, as the name would suggest, rather annoyingly clings to anything and everything when attempting to wrap your BLT. As someone who rarely uses cling-film due to the absolute faff of it, I can’t quite master the art of successfully sectioning and wrapping cling-film.

    However, cling-film is ideal for wrapping fresh foods, especially sandwiches and cut produce. It’s great for preventing browning of cut apples for example, and maintaining the freshness of your sandwich.

    Cling-film is also great for wrapping acidic foods, as opposed to tin-foil. Acids in the foods, such as tomatoes and berries, react with the aluminium, leaving a strange blue residue. So, next time wrapping your tomato filled bloomer, you should perhaps opt for cling-film to avoid the harmless, yet possibly off-putting, blue residue.

    Despite not being the perfect fit for acidic foods, tin-foil does have its benefits. Being easier to roll out, section and wrap are givens, avoiding the battle with the difficult-to-use plastic film.  It’s also good at keeping harsh odours in, so if you’re an egg-and-cress fan, maybe opt for the aluminium option to avoid stinking out the staff fridge.

    Another benefit of tin-foil is that it’s a great heat insulator, keeping your melted-cheese Panini warmer than cling film ever would. Your sandwich can also be popped in the oven still wrapped in the foil to warm it up. However avoid the microwave with foil, unless you fancy setting the office on fire.

    So, there’s no real winner I suppose as both maintain a decent degree of freshness.  A bit inconclusive yes, my apologies, but it really depends on your sandwich preferences.

    However, there is an answer to which is most environmentally-friendly of the two. The best option of course is a reusable container, but if we’re choosing between wrapping materials, tin-foil is the winner on the sustainability front. It’s widely recycled, while the plastic cling-film usually ends up at landfill as it’s typically thrown away as domestic waste.

    So, whichever side of the debate you’re on, cling-film or tin-foil, there’s some of the facts. Either way, may you enjoy your lunch, which is, let’s be honest, the best part of your working-day. Happy Lunching!
