Gaylord Liners are used for many applications

Posted by on Mon, Apr 6th, 2015 at 1:01 pm

A gaylord box is a pallet-sized box, typically cardboard, that is used for storage and shipping of bulk quantities.

In most cases, the products being shipped within a gaylord box are enclosed in an inner plastic bag that is used to protect the contents of the gaylord box. Those large bags, or liners, can have a variety of names: gaylord liners, tote liners, bin liners and combo liners are the most common.

They’re designed to protect the product from outside pollutants, toxins, and other contaminants during processing, storing, and transporting. Therefore, they must be strong and tear-resistant. These liners are used for many different packaging applications such as food packaging, resin products, color concentrates, chemicals, powdered products, pharmaceutical products, metal particles, and many more.

Depending on the product the liner is protecting, they are available in a wide array of structures. A few questions to consider:

  • Do I need low density resin, or high density resin?
  • Does it need to be bolstered for added strength with compounds like hexene or metallocene?
  • Does the liner need to be USFDA approved?
  • Do anti-stat properties need to be added?

Gaylord boxes come in a wide variety of shapes and sizes, and therefore, so do gaylord liners. When requesting a quote for a gaylord liner, you’ll need to know what size box you’re using. Measure your gaylord box by width (W), length (L), and depth (D). A good rule of thumb for figuring out an appropriate liner size for your box would be the following: See diagram.

Gaylord Box-2
  • Width (W) of the liner = Box width + 2 inches
  • Length (L) of the liner = Box length +2 inches
  • Depth (D) of the liner = Box depth + half of the box length + 12 inches.

However, you may need your liner size to be larger if you plan on tying off the enclosed product at the open end of the liner. It’s probably best to inform your sales representative not just of the box dimensions, but also how you’ll be shipping/storing your product so they can make a recommendation of the liner size you’ll need.

Some common gaylord liner sizes include:

  • 52 x 44 x 96 x 1.25 mil (thickness)
  • 52 x 44 x 96 x 2 mil
  • 50 x 38 x 90 x 3 mil
  • 50 x 44 x 76 x 4 mil

Posted by on Mon, Apr 6th, 2015 at 12:43 pm
thumbnailcafpaetc-resized-600Custom printed pallet covers are the sure fire way to advertise and improve load appearance while preventing pallet tampering and reducing freight damage. Freight damage can easily occur by your freight being loaded, unloaded and reloaded several times, in and out of warehouses and into and out of different trucks before delivery. The more times your freight is handled, the greater the chance of damage to your freight. Pallet covers help to reduce any damage to your freight so it arrives to you in the best possible condition.

In an industry such as the pellet fuel industry, a pallet cover can serve many purposes. You’ve got to keep your products dry during transportation and outside storage, in addition to ensuring your bags are clean for your customers. At the same time, you can show off your logo and company name with sharp vibrant printing that looks good even under the toughest conditions.

Ever wonder what is under those pallet covers when walking through big home improvement stores like Home Depot? Printed pallet covers become a great reminder to your customer to pick up another load of pellet fuel bags, all at a low advertising cost.

When purchasing pallet covers your opportunities are endless. Heavy-duty pallet covers are made specifically to fit your load size. Plus, film is available in many colors and your company logo can be printed on the front and back of the pallet. Any knowledgeable sales representative can be a valuable source when trying to decide on the best pallet cover for your specific application needs.

POLYETHYLENE 101 “Flexographic Printing”

Posted by on Thu, Apr 2nd, 2015 at 8:55 pm

Bold, Sharp, Eye-catching Packaging with Flexographic Printing

In this day and age high-end printing and eye-catching graphics are a necessity in the packaging industry in order to have a competitive edge and produce brand recognition with customers. Ever wonder how your package is printed with such accuracy to present that “wow” factor? The form of printing is referred to as Flexographic Printing, a modern day form of printing that can be used on many substrates including Polyethylene film.

The process of Flexographic printing using safe inks was approved by the Food and Drug Administration in 1949 and requires a three-step process of platemaking, mounting, and printing.

  • Platemaking can occur in three methods, the first of which is plate development using light-sensitive polymer. The second method uses a computer guided laser to etch the image onto the printing plate. And the third method requires that the plate goes through a molding process.
  • Mounting is a process used to ensure an accurate picture image. For each color to be printed, a plate is made and eventually put on a cylinder, which is placed in the printing press. Mounting marks are put on flexographic plates to help with precise alignment on the cylinder. These marks are key to aligning each color in the printing press. Equipment is extremely important at this point in the process as highly accurate and specific machinery is made for mounting these plates on the printing cylinders.
  • Printing is the final process in flexographic printing and produces the end result of a sharp looking package. The process requires that a positive mirrored master of the required image is created as a 3D relief in a rubber or polymer material. The image areas are raised above the non-image areas on the rubber or polymer plate and ink is transferred from the ink roll to the anilox roll where excess ink is removed before inking the printing plate. The polyethylene film is finally pressed between the plate and the impression cylinder to transfer the image.

Next time you’re admiring your bold printing and graphics on your polyethylene package or looking for a new and improved look for your package, remember that flexographic printing can achieve the best results. This complex printing process is the key to producing a polyethylene package that your customers will continue to recognize!


How Polyethylene film is made

Posted by on Thu, Apr 2nd, 2015 at 8:51 pm

The process for making polyethylene film and bags is called extrusion. This process starts with melting down small plastic pellets, ( called resin ), until they become molten and pliable.



The molten plastic is pushed, ( extruded ), through a circular die to form a continuous tube of plastic called the bubble. The bubble is inflated with air to the desired diameter and drawn vertically up a tower giving it time to cool before it is flattened to its lay flat width. The thickness of the film is controlled by the speed at which it is pulled from the die. The width of the film is controlled by the amount of air inserted in the bubble.



Film color can be changed in the molten process by adding resin pellets that contain colored pigment.

Many things can be done during this “inline” process. A printing press may be printing images, instructions, warnings, company logos, ect.. on the film. A bag making machine can seal and perforate the film to form varying lengths of bags on rolls. The film can be cut and separated for individually cut bags. You can also add vent holes, which are punched through the film in a variety of patterns and sizes.

The inline process has some further processing limitations. If the film requires more technical alterations then rolled film will be taken off the extrusion line to be further modified in what is known as out of line converting. Here is where you see Process printing and laminating, in addition to process of making sideweld bags, reclosable bags, and wicketed bags, is done out of line.

Polyethylene Packaging 101

Posted by on Thu, Apr 2nd, 2015 at 7:51 pm

Resins…. Film thickness…. Tensile strength…. Impact resistance…. What do all of these terms mean to you when purchasing your polyethylene bags?

Unless you are a poly salesman or have a degree in Plastics Engineering, the terminology used in the industry probably makes your head spin. To assist you, we’ve created Polyethylene Packaging 101.


You may find it overwhelming with all the different resins available these days. How does one choose when you have octene, metalocene, butene, hexene, etc… A knowledgeable sales representative will be able to help determine what grade to use. Each grade has different characteristics and choices should be based on applications. Understanding resin properties is critical in formulating the right product for your specific application.

Film Thickness (Gauge)

Polyethylene film thickness is measured by thousandths of an inch, or milli-inch. The thickness of the bag does not always correlate into strength. A heavy gauge bag is not always strong. Most often it is a combination of resin grade and gauge relative to the application. A 2 mil octene linear bag will have more strength than a 2 mil butene linear.

Tensile Strength vs. Impact Resistance

  • Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking. Why is this important?

It’s important to have a plastic bag that is strong enough for your application. A plastic bag that holds 50 pounds of material must have adequate tensile strength, otherwise the bag will end up breaking.

  • Impact resistance is a material’s ability to resist shock loading. What does this mean?

Basically it is the film’s ability to resist being punctured. A punctured bag may result in contaminated goods or product loss.

When choosing the correct gauge and resin formula it is important to consider how tensile strength and impact resistance are relevant to your packaging application. An example that everyone can relate to is a garbage bag. I’m sure most have had failure in a garbage bag whether it breaks when lifting out of the can (tensile strength) or waste material punctures holes in it (impact resistance). With all these variables in choosing the correct formula for your polyethylene package, having a knowledgeable salesman is vital.
