Airtight keep everything fresh for camping

I bought these for packaging small 3d printed parts that I have sold. These bags are perfect to keep them packaged and secure with the added bonus of looking professional. They can be used as a resealable bag or, with the addition of a bag heat crimped, an airtight bag that then become resealable.

Great product

This stack of mylar/foil lined grip-seal pouches arrived neatly stacked, wrapped with a rubber band and placed into a larger self-stick clear plastic bag. They look to be made well and from the dozen or so I’ve had a closer look at, they’re all consistent in size and quality. They’re not difficult or awkward to align while closing the pouches off, it just takes a light squeeze, and they click closed giving a reliable airtight seal.Most other listings selling similar pouches will typically list the external dimensions alongside the internal pocket dimensions just to give people a better idea of how big the actual sealed section is. Which is especially nice on pouches like these that have the extended tops for heat-sealing, which makes them seem larger than they really are. The advertised external dimensions of 7cm by 10cm are close enough to what you get, and I measured the internal pocket myself and found it to be 6cm by 6.5cm once you exclude the grip-seal and extended opening of the pouch.Each pouch has a slightly longer opening than is strictly needed and has pre-cut tearaway sections as shown in the images. Both of which are intended to make it possible to heat-seal the tops closed if needed. I don’t have a dedicated sealer for small things like these, but I was able to just use the heater from my kitchen vacuum sealer and the seal was clean, airtight and very easy to do. After it cooled off I couldn’t physically get enough of a grip to tear the seal open and the two pre-cut tear tabs worked great at getting the pouch open again without ruining the grip-seal section.Personally I think these are pretty much ideal for sending small quantities of screws or other small items to people. They’re also great for organising and packaging small kitbashing pieces for giving to friends for their custom Warhammer units, both 3D printed resin and spare sprue bits.The matte black design would make these especially good for sticking a custom sticker with a nice logo onto if you happened to be running a small business producing small hand-made goods that needed professional looking packaging. The first things that jump to mind are bespoke resin-crafts like custom dice or speciality keycaps for keyboard enthusiasts, but the possibilities are endless assuming you can fit it into the pouch.The current price of £8.99 for a hundred bags makes these quite a bit more expensive than some of the alternatives available on Amazon at the moment, but otherwise I have no complaints or issues with the bags themselves.

Priced: £8.99These are well made fun looking bags, with silver inside and colour gradient outside. The seal seems good. Price is reasonable.Unfortunately they have a strong chemical smell to them. They are sold as food-safe but I don't really think something that smells like that can be food-safe which is my reason for the low rating.
