Types of Stretch Film

There are many brands and configurations of stretch wrap film in the market today, as a matter of fact there are too many and its confusing to say the least.

Broken into two main categories of Hand Stretch Film and Machine Stretch Film depending on how the product is applied the rest of the variations are focused on gauge, manufacturing and application.

What is Hand Stretch Film?

Stretch film designed specifically to be applied manually is referred to as hand stretch film. It is also referred to as hand film, hand stretch wrap, hand wrap or manual pallet wrap. It is typically utilized in lower volume packaging operations. However the efficiency of manual stretch wrap packaging should be regularly re-evaluated against potential benefits of upgrading to a machine applied films.

Choosing the right stretch applicator will result in more efficient and cost effective packaging operations.

What is Machine Stretch Film?

  Flexo Printing Equipment for Industrial Products

  Flexographic printing is a method of direct contact printing. A flexographic (flexo) printer consists of multiple wheels that work in unison to pick up ink from an ink reservoir, deliver the ink to a printing die or plate, and roll the ink onto the material being marked.

  Flexo printers are an excellent choice for these types of printing applications:

  • The printed message does not change often

  • High quality logo printing is desired

  • Printed logos or messages are large

  • Specific colors are required (e.g. Pantone colors)

  • Printing is only required for short production runs

  • The budget for printing equipment is limited

  • Simple/low-tech printing machines are desired

  Industrial Printing Applications

  Pannier flexographic printers are used for printing text and high resolution graphics on flat materials such as metals, rubber, building products, textiles, and packaging products.

  The most important consideration when purchasing a flexo printer is the requirements of the printed message(s). How large is the overall size of message to be printed? How often must the message repeat on your material? The answers to these questions will determine the width and circumference of the print drum needed for your printing job.

  The Pannier Super Ink Print-All uses a universal frame that can accommodate wheels of several different circumference sizes. As shown in this image, the same size message can be printed with three different print wheels, but increasing the circumference of the wheel increases the space between each repeat of the print.

  Flexo printers use either one or two rolls to pick up and apply ink to the print wheel which holds the printing plates or dies. The wheels are tied together with a chain and sprockets so that they turn in unison. The friction of the print wheel making contact with the moving material is what drives the rotation of all the printer's wheels.
