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?


Stretch film designed to be applied with a stretch wrap machine is referred as machine stretch film. It provides many advantages over hand film including: faster and more efficient packaging, reduced packaging material costs, safer application, more secure loads and more.


Common Machine Stretch Film Types




Blown Stretch Film




Cast Stretch Film




Pre-stretched Film




Specialty Stretch Film




The basics of the stretch wrap world are that the heavier your load and the farther it travels the more film you will require to secure it. With this in mind the process requires knowledge, experience and expertise to select the most cost effective solution for your shipping requirements.


What is Cast Stretch Film?


Cast Stretch Film, otherwise known as Cast Film or Cast Wrap, is manufactured using the cast extrusion process.


Typical Characteristics of Cast Stretch Films




Excellent Optics




Clear




Glossy




Superior Tear Resistance




Quiet Unwind




Consistent Cling




Consistent Film Thickness




What are Pre-stretched Films?


Pre-stretched film is film that has been stretched (or pre-stretched) during the manufacturing process and then rolled onto cores for customer sale.


Pre-stretch Film Benefits:




Safer and easier operator application




Less operator effort required to wrap pallet loads




Less waste to landfill




Reduced neck down eliminates revolutions and trips around the pallet




Lighter rolls reduce operator fatigue and staff loss time injuries




Pre-stretch films are recyclable




Pre-stretched film is strong, consistent and stable




What are Specialty Stretch Films?


Specialty stretch films are designed to answer very specific packaging needs that more general purpose stretch packaging products cannot accommodate. A small sample of some specialty stretch packaging films are below.

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.
