Smelly Proof 4X3 Stand Up Storage Bag

The Tight Vac 57 Liter Storage Container holds 45 grams (28 grams per oz) or .57 liters and is a patented partial vacuum-sealed storage container that keeps items fresh up to 3x longer than conventional containers. I chose the opaque black can and lid to sell because it is what I use to limit UV degradation. I think this is a great inexpensive bulk container and I use them, but, in my opinion, the marketing is a bit of a reach. Since I use them, I can tell you with authority: They are NOT smell proof, and they DO NOT vacuum oxygen OUT of the container (oxygen degrades ALL organics) and you DO need a humidity control system for a long storage cycle. Still, for the size and price, Tight Vac's are a great value!This is what is said in the marketing about the Tight Vac 57 Liter Storage Container: -Tired of your food going stale just days after you have purchased it? How about those cookies you bought last week – Taste a little strange? Looking forward to those Cheese puffs you bought Two days ago? But they aren’t crunching anymore?

OK, so, really, the answer is, No, but, here's the marketing: The United States patent office granted us a patent on a vacuum container - Our Vacs create a PARTIAL vacuum - The same volume of air as the cap is removed and for human purposes this is enough to keep most goods fresh and edible for long periods of time. For the engineers out there technically speaking there is no vacuum until the cap is pulled upward without pressing the button. Either way the Vacs will keep goods fresher for longer and prevent weevil and bug infestations. This reality is why globally we have sold over 10 million Vacs without advertising. No batteries or electricity required!Are the Vacs smell proof? OK, so, really, the answer is, No, but, here's the marketing: The Tightvac patented system is able to preserve goods for 1 year and beyond by allowing products to breath and degas. Almost all food goods are smell proof inside the Vacs, however some products like freshly roasted coffee and medical herbs may degas, leaking their odor. Our 2 way valve allows gas build up to slowly escape - without letting oxygen in. This is one of the main reasons it can preserve goods for long periods of time.Note: Medical herbs that are sticky and smelly we recommend using a strong zip lock bag inside the Vac. This helps contain the smell and keeps the area clean where the body and the cap meet. This is essential to create a smell proof situation. The sticky resin often created by these products can compromise the open and close system, causing the caps to crack when opening and closing under such pressure of a glue like substance. Keep these areas free from resin buildup. Use a product like Grundge off. Thus maximizing the efficiency of use and longevity of the Vacs.Is it moisture and oxygen free? OK, so, really, the answer is, No, but, here's the marketing: Yes the Tightvac patented system keeps moisture and oxygen out - these elements cannot enter the container unless you decide to take the cap off. Right, except by use of the word "vacuum" you are lead to believe it is without oxygen, oxygen oxidizes, or degrades, organic matter. This container leaves PLENTY of oxygen inside the container.Are the Vacs durable? How long will they last? Yes the Vacs are made with NSF and FDA approved PS # 6, this plastic is very strong. These days shipping methods are very rough, packages being thrown, automated systems dropping huge parcels on top of smaller ones. If your Vac arrives damaged please report this IMMEDIATELY UPON RECEIPT for a part or full replacement.My cap seems loose? We offer 10 different sizes and 3 styles of Vacs - Solid - Clear and Tint. Often a Solid and Tint Vac will have a slightly looser fitting cap then a clear model. It is a misconception that a tighter fitting cap is working better or holding more of a seal. Loose caps function just as well and will tighten with time and use.How should I clean the Vacs? Hand wash only - Use mild or natural cleaners. Do not microwave or put in dishwasher. Always keep the interior of the cap and the top of the container clean. This will ensure easy open and closure.Need a bit more room? Try TV4!Made in China
