Ultra Clean Paper supplier

Ultra Clean Papers from Flexlink LLC

October 3, 2019Posted by Dale Schott

As you probably know, Flexlink supplies a range of ultra-clean, low ash, low chloride and low sulfate specialty papers for interleaving, archival and other applications. Usually, these papers are used in highly specialized applications.

In one recent application, an industrial customer was looking for a separator tissue to go between their conveyor and the product they process. The customer's end product goes into an oven and is heated at an extremely high temperature. The light-weight tissue enters the oven with the end product, burns and becomes an impurity in the final product. Therefore, less ash results in higher purity for this customer's final product.

With most papers, fillers such as clay create more ash in the paper. The amount of ash content can be measured and determined at the time the paper is manufactured.

At 15 lbs. per 3000 sq. ft. (24gsm), Flexlink supplies a natural tissue with an extremely low ash content (< .7%) without acid washing. Even though the paper's residue is not removed from the end product, the final result is a high purity end product that increases the customer's value proposition and overall profitability.

Flexlink can also supply light weight tissue with chloride levels as low as 30ppm and sulfate levels below 100ppm. Additionally, the firm supplies papers, tissues and boards that are acid free and lignin free.

Regardless of your unique tissue, paper or board need, call Flexlink LLC at 216-283-6107 to discuss some of the purest and cleanest papers available in the kraft paper market.

Flexlink's Moisture Barrier Products for Steel Coil Packaging

Solutions to Prevent Corrosion for Metal Coils

September 20, 2019Posted by Dale Schott

Whether you are looking to prevent corrosion, provide a professional appearance to your metal coils or improve your efficiency in the plant, Flexlink offers the barrier packaging solution to achieve your goals in both the ferrous and non-ferrous metals markets. Below you will find a brief summary of our capabilities.

Flexlink offers a full array of laminated and scrim reinforced papers and fabrics to protect your steel coils. Both papers and fabrics can be custom printed with company logos, safety information or other data.

In some cases, Vapor Corrosion Inhibiting additives or desiccants are needed to consume oxygen and prevent corrosion. Flexlink can incorporate these additives into VCI Stretch Film, VCI Fabric and Steel Wrap. Meanwhile, VCI Bags that can be slid over the top of steel coils with or without the use of desiccants are also offered.

Flexlink understands that steel mills and service centers can be very rugged environments. While we offer polyethylene coated papers and asphalt laminated papers which are often used to wrap coils or as coil end-caps (aka donuts), sometimes these materials are not strong enough. Therefore, scrim reinforced papers, scrim reinforced film laminates and scrim reinforced woven fabrics are offered to prevent tearing when wrapping around steel edges and sharp corners.

Regardless of your unique need, call Flexlink LLC at 216-283-6107 and let us help you solve your steel packaging problems.

Glass Interleaving Paper Quality Control Considerations

September 30, 2016Posted by Dale Schott


There are five major factors that influence how often defects occur and how severe defects are when they do occur in glass interleaving paper. Luckily, the last two factors are controllable and can eliminate the risk associated with the first three factors, which are uncontrollable.



  1. Humidity - humidity increases the risk and severity of defects
  2. Heat - the warmer it is (either b/c of ambient temperature or because you are interleaving warm glass), the greater the chance of of chemical reactions which lead to defects
  3. Time the glass is interleaved - the longer you leave the paper in the glass, the greater chance of a defect

Controllable - Can Eliminate Risk from #'s 1,2,3

  1. Thickness of the paper relative to its pH - thin papers need a very low pH to avoid problems, thicker papers can have a higher pH
  2. Resin content of the paper and pulp cleanliness - limiting resin levels and other pulp cleanliness characteristics can combine with the pH to eliminate your risk

The first three issues are uncontrollable. While some clients have added equipment to extend cooling sections and/or added extra climate control equipment which also comes with higher utility bills; this is not required if you use the proper paper.


The heat and humidity can vary by time of the year or even from week to week or day to day. It is prudent to investigate if your defects coincided with unusually humid days at your facility or high humidity at your customers' facilities.


We have proven time and time again that controlling the pH and resin levels can eliminate these defects completely, Whether you buy from Flexlink or not, please be sure that the pH and resin content are measured multiple times while each order of your paper is being manufactured. Also know that if you do not use a paper produced specifically for glass interleaving, the paper mill can add chemicals to your paper any time they want. MG paper is used for bags for muffins, donuts etc. With this in mind, paper mills will often incorporate chemicals to decrease cost and increase efficiency assuming that the paper they are producing will go into bag applications.


In paper manufacturing silicone based defoamer agents can decrease cost and are therefore gaining in popularity. Unless the paper mill producing your paper is custom manufacturing a glass interleaving paper specifically for this application, they are likely to maximize efficiency without regard for how chemical changes can impact your products. In fact one of our current customers first came to us with a defect that was happening for months. Our laboratory analyzed the defect and determined that there was a thin coating of silicone on every window. As it turned out, the paper mill had switched to a silicone defoamer with the goal of decreasing their cost. The glass defect was costing hundreds of thousands of dollars annually. This customer switched to Flexsheen® and has not had an interleaving related defect since that time.


Whether you buy from Flexlink or not, please give the issues above some thought. Our Flexsheen® line of products is not the least expensive paper on the market. However, the cost of random QC problems, you will find that the Flexsheen® has the least total cost of ownership of any paper that you can use for glass interleaving.
