    hot cold food packs Great pack catering hours heat more
    1 out of 1 found this review helpful

    I use these for a school lunch catering company. Initially these worked great, they hold the heat very well. However, over past six months, I have had to continually order more because they develop leaks. I am hoping to find a brand that will last longer.

    Thank you for the review, Donna. We are sorry these hot / cold packs have been leaking for you. We would like to address this issue. A Customer Solutions Representative will contact you shortly.

    This reusable pack is absolutely fantastic. Be careful not to overheat, and always use a paper towel between the pack abd your skin but this prodyct is a winner!

    Pack in use.

    This is a very good quality hot and cold pack for the price. I have a carrier that I used to take food to potluck dinners. This works very well

    this is a very big thermal hot/cold pack. it's great for anything. i use it mostly as a cold pack in a cooler, but it would work just as well to keep food warm while you transport it. even for first aid if you're in a pinch

    from Sweet Pea's Cupcakery Cafe Posted on

    We use these as ice packs and they have been a great addition to our delivery company. We have not tried them as hot packs yet but are confident they will be just as effective.

    from TIme Makers Posted on

    The product works good but we had a few problems. When we received our order there were no instructions on how long to warm it. The product itself said do not over warm but nothing to say how long that was. So out of the threevwe ordered, one split...guess we over warmed. Out of the two we have left, they do what they say and keep food warm in delivery bags. We will probably order morejust going to see how long the last two go before they split and leak.

    This is an excellent product! Great in keeping foods hot & cold in the delivery process. Highly recommended! Webstaurant has just about everything you need!

    from Tina Avery Posted on

    These packs have been amazing! We needed a way to create a pizza warming station without running electricity. We heated up a dozen packs and placed them under inverted sheet pans. The pizzas on top stayed warm and safe. We changed them out about every 30 minutes to make sure they pizzas stayed hot, but we couldn't have done it without these packs. Now they're getting daily use on our food truck to keep sodas fridge cold. 2-3 packs with a little cool/cold water to transfer the cold and room temperature sodas are drinkable in 20 minutes or less. We're saving considerably per day on ice.

    We use those for catering and they hold temperature well. Either cold or hot and used in a cooler or cambro they last for hours. After a long day of catering they are still half frozen.

    The Thermal Hold and cold pack did a great job. We use them to keep our hot food hot when transporting food for our catering events. Will order again.

    from Wes & Nita Posted on

    This hot/cold pack is a little smaller than a 1/2 pan lid (for size reference) and keeps product remarkably cold for a very long time. I'm quite pleased with these. Great for catering.

    I deliver Meals-On-Wheels. We use igloo-type coolers to deliver hot meals. Each stop to deliver a meal means the cooler is opened to retrieve the meal. This means that the lid is opened 20 - 25 times over the course of a route. These pads do a great job of keeping the meals warmer, longer. I have ordered a dozen or so over the past two years and have been very pleased with them. Recent concern. One of my pads developed a leak. I ordered two new pads. When the box arrived it was obvious that one of the pads had leaked during shipment. Webstauranstore promptly shipped a replacement. It looked okay, but upon first use it also leaked. To their credit, Websturantstore is sending a second replacement. I don't expect the pads to last forever, but I'm concerned about this recent failure rate on new pads.

    I used these as hot thermal packs when catering my own wedding. Since then I have used them as cold packs numerous times. I keep them in my freezer at all times. They have remained frozen for up to 24 hours in a sealed food carrier.

    This hot pack works great! Just microwave it for a few minutes, and it stays hot for a few hours in an insulated bag. Also works great as an ice pack.

    from Chef Stephanie Posted on

    I transport food for a School District. I purchased these to keep the foods hot. I was very pleased with these. They keep the foods at the proper temperatures for at least 3 hrs or longer. I haven't tried them for cold stuff yet. I would highly recommend these.

    STELLAR product. These hot packs maintain their temperature for a long time - I've used them for 2 hours in an insulated cooler bag (also purchased on this site) and they're still hot. Be cautious when handling as the product instructions state - they can burn if you're not careful. And they can puncture which will let all the fluid out so they're of no use at that point. I will be purchasing more of these pronto because they're that awesome!

    I use these great little packs daily. They hold heat or chill for over an hour, and are very soft and flexible, so can be wrapped, bent or otherwise shaped to fit any transporting container. They can also go under a serving tray or platter to help keep the temperature.

    from frills catering Posted on

    There thermal packs are a nice size and heavy. It is printed on the case not to overheat but I can not find instructions on how long to heat it. I do plan to order a few more.

    from thetammster Posted on

    Really like these. Would recommend using two at a time if carrying full size pans. Great for keeping things steamy during transport. Will buy more for a variety of containers.

    Posted on

    Even since receiving my thermal packs, I have used them almost every day. We heat them and then put them in the coolers with our sandwiches we send out on catering orders. They work great, keeping the food hot for hours.

    Ordered 12 of these to be used in insulated food travel bags. Unfortunately, they did not come with instructions. I contacted the company via the phone number printed on the product. They indicated that warming for 2 minutes, on high setting, in a microwave would heat the MicroCore sufficiently. I realize that microwaves vary but, I had to heat one for 8 minutes to get it hot. However, I left it on my desk top, totally exposed and an hour later it was still very warm. A practical product to use in an insulated food bag. It would have been handy to have some instructions for use and care enclosed with the product.

    from Associated Posted on

    Bought a dozen or so of these. Have used them for hot & cold foods for my food carriers. Freeze easily, as well as heat easily. Thick plastic that holds up very well in many conditions. Mine are still in great condition.

    from Wedding Dreamer Posted on

    This hot pack works just like it says, and it is very easy to use. I have only used it hot, but I put it in the microwave for 7 minutes and it is good to go for hours. I am going to buy another one.

    from Sweet Swirls Cupcakery Posted on

    I love these. I use them when making food deliveries and have burned my hands not realizing the product was still so hot. I have never froze them but I am sure they will perform just as well.

    from Almost Home L.L.C, Posted on

    I only ordered one of this item to try but will order several more. The size is good and I like the fact that it can be used for hot or cold items.

    These Hot cold packs were quite the surprise, I have never had a pack that went from Frozen to hot and they work incredibly well - Held a transported cheesecake for 4 hours in direct sunlight and still was ice cold !

    from JONABELLA CATERING Posted on

    Sometimes insulated carriers are just not enough to maintain transported food at temperature until serving. These packs heat in 5 minutes in a microwave, add a minimum of weight to the carrier and wipe clean. They also stack and store easily. A superior product.

    from Double Deuce Tailgaters Posted on

    This pack can be used successfully with my name brand travel dish, without the name brand price! I look forward to packing it with my hot or cold items.

    Posted on

    These packs work really well to keep food items hot or cold for transporting to catering jobs. They are nice because there's no mess to deal with.

    Posted on

    I bought one to test it out, and it have to say I will be buying more! Works great to keep food warm temporarily while on deliveries or for an afternoon picnic.

    Posted on

    I purchased several of these to use with the insulated food carrier and they work GREAT! I just ordered a dozen more and three more of the carriers. Highly recommend.
