Foods and drinks do not taste good when they do not retain the desired temperature. Your hot soup will lose its flavour when it loses heat. Similarly, your favourite wine gives the best sensation as a chilled drink. But, when you carry your food and beverage in ordinary bags, it is not easy to maintain the temperature. That is why you need to use cooler bags, also known as insulated bags. Let us learn more about cooler bags.

SANNE supply professional and honest service.

Promotional Cooler Bags, Insulated Imprinted Cooler Bags

Coolers have changed dramatically over the years.  Perhaps the biggest and most notable change is the evolution of the cooler bag from the old-fashioned hard-bodied, rigid ice chest style coolers.  While these are still available and well-suited for certain applications, the cooler bag is an excellent, modern alternative that is better suited for everyday, recreational use.  Subsequently, promotional cooler bags have become a popular advertising gift and one of ArtPromos.com's big sellers.

If you're used to the standard ice-chest, it might be helpful to understand some basic facts about the promotional cooler bag and why it's such a great alternative and popular advertising gift:

* Cooler bags rely on a different type of insulation than ice-chests.  The ice chest uses Styrofoam to prevent the transfer of heat between the outside and the inside.  Styrofoam is an excellent, lightweight and economical insulator.  However, its biggest drawbacks are its bulkiness and its fragility.  This necessitates being surrounded by a protective hard shell which adds even more bulk and weight to the cooler.

By contrast, the cooler bag relies on polyurethane foam and foil to prevent heat transfer.  Polyurethane foam has the ability to form a powerful barrier to heat exchange and is much less thick and bulky than Styrofoam.  Our promotional cooler bags have a layer of polyurethane foam sandwiched between a heavy fabric outer layer (such as polyester) and a foil inner layer.  Together these three layers perform as well as a thick layer of Styrofoam and are much thinner and lighter.

* Cooler bags come in a wide variety of sizes.  Because cooler bags are flexible, they can be manufactured in a greater range of sizes and even shapes than the rigid ice chest.  Our line of promotional cooler bags come in sizes just big enough to fit a small lunch (perfect for students and professionals), one baby bottle or two or three beverage cans, up to sizes that are big enough for 36-48 beverage cans or an entire day's worth of meals (ideal for a Saturday at the beach).  Whatever the task or event, we have the right size promotional cooler bag for the job.

* Our promotional cooler bags come with a variety of features. We carry models with all kinds of special features, including shoulder straps (for small to medium-size bags), telescoping handles and wheels (for large models),  pockets for small food and personal items, flexible mesh pockets for promotional water bottles and beverage containers and more.

* We carry a wide variety of colours and styles.  Our promotional coolers are available in most every basic color well as black.  If you're trying to find one that complements your logo, we can help you choose the perfect model that will give your customers a positive and long-lasting impression of your company.

* Cooler bags should not be used with ice cubes.  If you've ever used a rigid ice chest, you're probably used to filling it up with ice cubes to keep the contents colder, longer.  Ice cubes are not recommended for use with cooler bags because they can actually puncture and tear the foil inner lining of the bag.  Instead, keep the interior cool with self-contained ice packs.  They're safer and less messy, too.
