The LST-1616 is designed for easy and quick shrink wrap packaging. Users can produce products that have a factory fresh clean look and feel. The sealer/tunnel combo creates packages that are free from dust, moisture and fingerprints.

The L-bar measures 15.7″ x 15.7″.

The shrink tunnel is located underneath the L-bar sealer ensuring a small footprint.  The machine dimensions measure 44″L x 28″W x 44″H.

Why is using an L-bar sealer important for shrink wrapping?

Sealers designed for shrink wrapping will create a seamless seal (i.e. excess material above the seal is cut off).   Once a heat source is applied, and the material shrinks around your product, this will ensure a clean look.

See below and example of what NOT to do….here is a product that used the incorrect sealer to shrink wrap.

When you shrink wrap, the package should not have any seams visible.  See below:

How to Seal and Cut Using our Sealers

SealAndCut

Our latest post will be a quick refresher on what our “seal and cut” options are on our sealing equipment.   There are two types of seal and cut:  (1)  cutting excess material so that there is a seamless seal primarily used for shrink wrapping and (2) using a trimmer on a sealer to cut a bag that is too long or to make poly tubing.

For shrink wrapping, you will want to create a seamless seal with no excess material above the seal as you will be heat shrinking the material around your product.  Either use a hand sealer with a ROUND wire or purchase an L-bar sealer.  For more information about shrink wrapping, refer to our previous blog:  Shrink Wrapping 101.

For cutting a bag because it is too long, we have various sealers with sliding cutters.  Usually there is a blade on the sealer which will trim excess material about 1/4″-1/2″ from the seal line.  We carry hand sealers, foot sealers and our newest addition, band sealers with sliding cutters.  The band sealer HLC-1120LD which is equipped with a trimmer to cut off excess material!

HLC-1120LD is suitable for sealing all types of thermoplastic materials and bags. This unit is equipped with a trim scrap system for trimming excess material. The vertical configuration is ideal for sealing stand up pouches and liquid-type products.

Shrink Wrapping – Using an I-Bar Sealer

Check out our latest video on using an I-Bar Sealer for shrink wrapping.  An I-Bar sealer allows you to make professional looking packages in seconds with no mess or fuss!

Shrink Wrapping with a Shrink Tunnel

Adding to our Shrink Wrapping 101 post last month, we wanted to demonstrate how a shrink tunnel machine works.  It’s super easy and maintenance free and sooooooooo much faster than using a heat gun!

We have two dial settings:  one for the upper and one for the lower heaters.  Adjust the temperature and speed conveyor to your preference.   Note:  the faster the conveyor, the higher the heat.  Play around with the settings…this may take some trial and error.  Once your settings are set, place your item with shrink wrap packaging on the conveyor and voila!

Why Shrink Wrap?
Shrink wrapping is an excellent and easy way to package a product without the need to purchase a lot of expensive equipment.   Shrink wrapping provides:

  • Crystal clear sealed packaging
  • Protection from dust and moisture
  • Tamper proof packages

What Do I Need to Shrink Wrap?
All you need to shrink wrap is 

  • Shrink material which comes either as rolls of film or shrink bags
  • Hand impulse sealer (w/round wire), and
  • Heat gun

How Do I Shrink Wrap?

  • Insert your product between the fold of film or into a shrink bag
  • Using your sealer, cut off excess film and seal the ends of your film closed
  • Shrink the film on all sides using a heat gun

How Do I Determine the Right Film?

  • Measure the width and height of your product and add 5-10% to the measurement.  This provides you with your minimum shrink bag width.
  • Measure the length and height of your product and add 5-10% to the measurement. This provides you with your minimum shrink bag length.
  • For shrink film (usually sold as centerfold film), take the smallest figure of the two to determine the shrink film size needed.
  • If the size you needs is not available, a larger size can be used because shrink films will shrink up to 40% in all directions

Need to Shrink Wrap Faster?
If you are looking to shrink fast your product even faster, we have L-bar sealers which cut and seals two sides of the film in one motion.


YC-300HL  – 12″ x 18″
