BELCO Sealer-Tunnel Combinations


How to choose which Belco STC is right for you?

Belco manufactures manual and semi-automatic STC Combination L-Sealers and Shrink Tunnels capable of running production speeds of 5-25 packages per minute or 500,000 up to 2,500,000 packages per year. (Based upon one 8-hour shift.)

The STC 2016 "ECO" has a 20" Long x 16" Wide seal area and a shrink tunnel chamber opening of 18" Wide x 8" High x 24" Long. It is an excellent value priced shrink packaging system that is perfect for start-up operations or augmenting existing packaging lines. Use it for manual packaging applications that only require 5-7 packages per minute.

For faster applications and semi-automatic operation, the Belco STC 2016 Standard or STC 2520 should be your choice.

The STC 2016 Standard has a sealing size of 20" Long x 16" Wide and a tunnel opening of 18" Wide x 8" High x 24" Long. The STC 2520 has a sealing size of 25" Long x 19" Wide and a tunnel opening of 21" Wide x 8" High x 36" Long. These machines allow for faster production speeds and the ability to perfectly shrink more difficult products.

All models employ a precision controlled hot wire system with a simple Nichrome wire element to produce the front and side seals. Setup is accomplished with the simple adjustment of the wire temperature and impulse time controls. Broken wire down time disappears as these controls make production setups and change-overs simple, reliable and predictable.

Hot Knife Sealing technology with Watlow digital temperature controls for the front seal and side seal is available on the STC 2016 Standard and STC 2520.

Size – The first consideration is the size range of packages you need to wrap. If they will not fit into the seal area, you can’t wrap it... if they won’t fit into the tunnel opening, you can’t shrink it. It’s important to consider the entire size range of packages you want to shrink wrap.

Low profile packages can be sealed in seal areas that are much closer in size to your actual package length and width. Taller packages will require larger seal areas.

When choosing which tunnel opening is correct for you, a general guideline is to allow 2 inches of clearance between the top and sides of your largest package to the top and sides of the inside tunnel dimensions. Ask your Belco sales representative to recommend which machine is correct for you based on the maximum length, width and height of your product.

Product Package Complexity – Do your packages include irregularly shaped designs, windows or high profile cube boxes or cartons? If so, some of your products may require more precise air control to maintain quality shrink packaging. Therefore, you may want to consider the Belco STC 2520 or maybe a Belco "Re-circulating Air" tunnel along with the appropriate Belco L-Bar Sealer.

Speed – Do you require standard or high speed productivity? You should consider how many packages you need to produce to meet peak demands as well as satisfy regular production schedules.

Conveyor Belts or Rollers – If your range of package sizes is from small to very large and heavy, rollers should be your choice. If you're going to be shrink wrapping very small to medium sized packages or loose multi-packs, a Teflon mesh belt conveyor may accommodate your needs.

Productivity Options – Belco offers many options that can be added to your STC which are designed to meet your specific production requirements and enhance your productivity. These include: powered film unwind with adjustable inverting head, air-operated seal arm or Magna-Lock hold down system and power take-away conveyor. Please ask your friendly Belco representative to assist you in determining how each of these options can best meet your specific needs.

Belco will be happy to discuss and help you evaluate what your specific needs may require. You can count on us to provide you with the expertise you expect. Whatever your needs, you can be assured that Belco has a shrink packaging system to meet your requirements.

Which ever Belco machine you choose, you can be confident that it will be productive and profitable for you!
