Compare Our Prices, Quality, and Selection
IMPAK Corporation has been a leader in packaging products for over 30 years. Because we specialize in flexible packaging, desiccants, and sealing machines, we have the best products on the market in these categories, and at the best prices. You will also find a much wider selection of these kinds of products to choose from. See how we compare to the "other guys" who try to do a little bit of everything.

Why single out ULINE?
Although other packaging companies have pointed out the well-documented reasons why some consumers urge others to boycott ULINE, at IMPAK we think that the reason to source your materials with us is simple. We'll offer a better price than ULINE's, and more importantly, a better quality of product. What you won't get is an 800-page paper catalog and free sports knickknacks. We are a company whose focus is on the technical aspects of quality barrier packaging. We are known for our ability to create structures from a wide range of materials like Mylar®, Aclar®, Surlyn®, and other specialized materials, including heavy gauge foils and high moisture barrier films such as our PAKDRY7500. And if you don't see exactly what you need in our online catalog, contact us and we will make it happen. We doubt that ULINE would offer that.
Tabletop Impulse Sealers

Impulse Heat Sealers such as our IPK Series are generally made with the same range of seal lengths by different manufaturers - between 4" and 20". It's the seal width that sets our IPK sealers apart. Other units give you a "string seal" of approximately 1.6mm (1/16") - thin enough to make you worry. With a 5mm (3/16") seal width, our IPK machines make a seal you can count on.
Comparing the 12" models (most popular seal length for these machines), as of 12/15/2023...
Model | Seal Length | Seal Width | Price |
---|---|---|---|
Generic | 12" | 1.6mm | $123.00 |
IPK | 12" | 5mm | $53.30 |
Their seal is 20% thinner than the 2mm seal below

Silica Gel Packets

IMPAK Corporation knows desiccants - it's one of our specialties! And though Silica Gel Packets can be found in lots of places, our prices are hard to beat. The table below demonstrates the difference between those who don't specialize in desiccants and those of us who do.
Size | ULINE Silica Gel | IMPAK Silica Gel |
---|---|---|
0.5 gram | $.0381/packet | $.0191/packet (50% less) |
1 gram | $.0438/packet | $.0309/packet (30% less) |
2 gram | $.0667/packet | $.0457/packet (31% less) |
3 gram | $.0875/packet | $.0680/packet (22% less) |
5 gram | $.1248/packet | $.0932/packet (25% less) |
10 gram | $.3433/packet | $.1561/packet (55% less) |
Stand Up Pouches

When it comes to flexible packaging, one of the most obvious differences between IMPAK Corporation and the others is our selection. We carry hundreds of different styles of pouch compared to the handful available from them. And even with the few bags you can get from those some-of-everything operations, we can beat their prices.
Take Stand Up Pouches like the ones pictured above. Depending on styles and sizes, our comparable pouches beat those competitors' prices by 5% to 15%!
And if you need a custom package, forget the others. We offer custom packaging, custom printing, and even custom laminations if you have really specific materials requirements. Unlike those others, flexible packaging is what we do.
Vacuum Seal Bags

Our food grade 8.5" x 13" V4R08513 Clear Vacuum Bags are a superior choice not just for vacuum sealing food items; they can be frozen, placed in boiling water, and used for heavy duty industrial applications. Compared to your standard polybags, these offer a fraction of the oxygen and moisture transmission rates with 2/3 the material thickness. That is source reduction and efficiency at its finest. And they are available at half the price of popular similar-sized bags found elsewhere.

Vacuum Sealers

IMPAK Corporation has a variety of vacuum sealers to fit any user and any budget, from small sealers for the home to commercial grade nozzle-style units to industrial scale chamber vacuum sealers.
Need a Home Vacuum Sealer to keep your food fresh? Look no further. The CounterMate Series Home Sealing System is recommended by our experts for its reliable quality, and there are several models to choose from. $260.00 will buy you a decent home sealer from ULINE, but for $158.36 you can get our comparable CounterMate Deluxe Home Vacuum Sealer AND a case of vacuum seal rolls, enough to seal hundreds of meals.

Or maybe you puchased an H-1075 Vacuum Sealer from ULINE and, like a lot of others we've talked to, that machine has not worked out well. IMPAK can replace that unreliable sealer with one of our EVS All-Electric Vacuum Sealers, dependable machines at a comparable price that provide a strong vacuum with no need of a compressed air source. Contact one of our sealer experts to ask about making this upgrade.
Not only do we sell vacuum sealers; we build them, repair them, and design custom models. Along with sorbents and flexible packaging, sealers are one of our areas of expertise. If your business needs an upgrade from a home sealing unit, look into the wide variety of sealers we offer.

Clay desiccant is a 100% natural, non-toxic, biodegradable, and environmentally safe way to keep products dry, and we have highly competitive prices on Small Clay Desiccant Packets. The table below shows an example of our per packet prices compared to a major supplier of shipping supplies.
