Therefore, placing eye drops in a thermal bag may adversely affect their stability, as the insulating nature of the bag may allow the temperature to rise, thereby exposing the eye drops to high temperatures. Eye drops usually need to be stored in a dry, cool, and light-proof place to avoid being affected by sunlight and high temperature, so as to maintain their efficacy and safety. If you need to carry eye drops when going out or traveling, you can choose a waterproof, moisture-proof, sun-proof small box or condom to store eye drops, and put them in a dry, cool place to maintain their good quality and effectiveness . In short, eye drops need to be stored in a suitable environment to maintain their efficacy and safety. Although the thermal bag can keep warm, it is not recommended to put eye drops in it, so as not to be affected by the high temperature. **Q: Would these work for repackaging dehydrated meals?** A: It is not possible to use the thermal insulation bag to directly contact the dehydrated food. The dehydrated food can be packaged in the thermal insulation bag to achieve the purpose of insulation. **Q: Do you have to use with ice packs or can this hold temperature by itself if an item come from the freezer to be shipped?** A: Never tried shopping without ice packs. With it being perishable I do all I can to keep it cold. I put the ice packs in the envelope with my mason jar. I use these disposable 2x2 inch ice packs. Works great together. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by H***R on August 17, 2025* Great product. Very helpful. Very functional. As advertised. ### ⭐⭐⭐⭐⭐ Simple and Effective Insulation Bags *by F***I on December 14, 2025* Lightweight, reusable, and do exactly what they promise. The metalized lining holds temperature well for groceries or lunch boxes, and they fold flat when not in use. Not fancy, but practical, durable, and worth it if you need reliable thermal insulation. ### ⭐⭐⭐⭐⭐ They are Too thin but it worked with other insulated items. *by J***E on November 26, 2025* Edit: It works with ice packs and an insulated shopping bag. If you use it together- it works PERFECTLY! 5 stars. Leaving old edit for chemical smell. Because after a while it goes away. So just noting be aware. However it works great. Giving 3 stars for item arriving on time. I needed these urgently but couldn’t get options for delivery to arrive in 2 days except this item. The item came nicely packed. However they are very thin as in,1/8 inches and smaller than the size listed 13” by 15”. They are more likely mail envelopes. I hope it will keep food cold for packaging. Also note they have a bit of a weird chemical smell. ## Frequently Bought Together - SMILCO Reusable Insulation Bags Thermal Box Liners Metalized Box Liners Lunch Food Box Shopping Bag Insulation Lining Waterproof Insulation Package (20 Pack/ 11 In x 15 In) - Polar Tech | IB 6 | ICE-BRIX & XTREME BRIX Cold Packs | 6 oz, 6" x 4" x 3/4" (Case of 48) - ZEAYEA 30 Pack Reusable Insulation Bags, Thermal Box Liners for Cold and Hot Food, Insulated Shipping Mailers Envelope Bags, Waterproof Insulation Package for Lunch Food Bento Camping Picnic, 3 Size --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/242250062-reusable-insulation-bags-thermal-box-liners-metalized-box-liners-lunch](https://www.desertcart.vu/products/242250062-reusable-insulation-bags-thermal-box-liners-metalized-box-liners-lunch) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
