Eco-Friendly Glues: Part One

Posted on April 30th, 2012 by L.D. Davis Industries, Inc

Eco-Friendly Adhesive Products

L.D. Davis Industries manufactures a wide variety of protein-based glues and liquid water-based glues, which are all eco-friendly, completely non-toxic, and easily recyclable. Today, we’d like to feature our eco-friendly protein adhesive products, which are also commonly called animal glue or hide glue.

Protein Adhesive

Eco-friendly protein adhesives have been around since ancient times, and are commonly used in bookbinding, woodworking, case making, and box-making applications. Protein adhesives are made up of just a few all-natural ingredients, which include:

  • Gelatin
  • Glycerin
  • Water
  • Epsom Salt
  • Corn Sugar

Since these raw materials are naturally recyclable, protein adhesives are also completely biodegradable. They will begin breaking down only weeks after being recycled back into the natural environment.

Background Information

Protein adhesives, (just a reminder, also known as animal glue and hide glue) come in cake form and must be melted prior to use. Protein adhesives are usually applied to a substrate by use of a wheel, roller, or pad. The term protein adhesives come from the type of gelatin used in the adhesive manufacturing process, most commonly called technical gelatin. The protein found in this gelatin is animal protein, historically extracted from the hides and bones of pigs and cattle, hence the alternate names, animal glue and hide glue.

We are proud of our protein-based adhesive line of eco-friendly glues. Not only are they already used in a wide variety of applications; they are easily customizable for a number of variables to increase their usage potential.

Book Binding Glue by LD Davis Industries

Posted on March 22nd, 2012 by L.D. Davis Industries, Inc

LD Davis Industries: The Book Binding Glue Standard

In the beginning, LD Davis Industries manufactured an adhesive product for the stenciling industry. However, as a smart and innovative company must, LD Davis Industries adapted to the changing business climate when necessary and altered its product to serve the box making and book binding industries. Book binding glue became, and is to this day, one of LD Davis’ premier adhesive products.

Book Binding Glue

Binderies use different types of book binding glue depending on the type of book and the binding process used. LD Davis book binding glue is a type of animal glue, which must be heated prior to use; however, it is different from a hot melt adhesive. Book binding glue is made up of the following raw materials:

  • Water
  • Corn sugar
  • Gelatin
  • Glycerin
  • Epsom Salts

Eco-Friendly Book Binding Glue

Once the raw materials are mixed together in a heated kettle, the animal glue material is poured into large trays to try, which creates cakes of about 10 pounds each. These cakes are then packed in boxes and sent to our customers, who melt the cakes down before use. Due to its ingredients, book binding glue is completely non-toxic, safe for the environment, recyclable and biodegradable. We like to call our book binding glue an “eco adhesive.

Whether they’re hard cover, paperback, or specialty bound, LD Davis Industries can supply the book binding glue to get the job done. Our book binding glue has been a standard in the industry for decades and will continue to be as long as books are printed!

Do us a favor: put down the E-Reader, Kindle, or iPad…pick up a book…and check out the quality book binding glue securing it together while you’re at it! To learn more about book binding glue manufactured by LD Davis Industries, please visit our website.

Customer Service

Posted on January 30th, 2012 by L.D. Davis Industries, Inc

We pride ourselves on excellent customer service at LD Davis. A large part of our competitive advantage, aside from manufacturing quality animal hide glue for over 85 years, is the fact that our salesmen make over 3,000 on-site, in-person visits to our customers each and every year. This personal, face-to-face attention shows our clients how much we really care about their adhesive application.

The following is a quick thank-you note one of our salesmen, Jeff Palmiter, received from a client of his that works at a large packaging company:

“Jeff,

Just a short note to express our appreciation for the effort you made to take care of our glue shortfall. Meeting our driver midway made a big difference in the timely delivery of the needed glue back to our facility as well as taking my call late last evening to discuss the possible scenarios to get the glue to Roanoke.

You displayed another example of a way L.D. Davis is above all the others.

Look forward to seeing you next week when we will conduct the glue tests.

Thanks again,

Kurt.”

At LD Davis, we will do everything in our power to ensure that our customers get the animal hide glue that they need, when they need it. The above communication came after Kurt discovered an unexpected shortage of their animal hide glue right before a big project. His salesman, Jeff Palmiter, went above and beyond to get him the animal hide glue that he needed to do his job correctly.

Clients cannot go wrong with LD Davis’ customer service or quality adhesive products. We have been manufacturing excellent animal hide glue and liquid glue, both eco-adhesives which are totally non-toxic and biodegradable for many decades. We also distribute hot melt adhesives, PUR glue and fugitive glue from respected companies around the country. We are here for your adhesive needs, no matter what.

85 Holiday Seasons

Posted on December 22nd, 2011 by L.D. Davis Industries, Inc

Raw Animal Glue Stenciling Product

85 holiday seasons.  That’s how many years LD Davis has been producing quality animal glue in the US.  Our 85th year is coming to a close and we couldn’t be more grateful for the past eight-plus decades of adhesive manufacturing.  Thank you to all of our customers, employees, and friends for helping us get this far.

In the Beginning

LD Davis got its start in 1926 inside a residential home in North Philadelphia.  Louis Davis Sr. began using raw animal glue in a product for the stenciling industry and grew the company into the premier animal glue manufacturer it is today, through strong competition and world events such as the Great Depression and multiple wars.

 

Expansion

By the time his son, Louis Davis Jr. joined the company in 1960, it had grown significantly from a small stenciling business, to rendering animal hides for adhesive manufacture, to a thriving business at our old Bristol, PA glue manufacturing facility.  LD Davis had grown to selling animal glue all over the country and in 1965, began selling internationally into Canada, Mexico, and South America.  In 1970 with Louis Davis Jr.’s development of Pink Special, a low-cost animal glue for rigid boxes, LD Davis solidified its role as the major animal glue supplier for the box-making industry.

LD Davis celebrated its 50th year of glue manufacturing in 1976, and the next year, Louis Davis Jr. took over the company after his father’s passing.  During his time as President, Louis Davis Jr. expanded international sales and also moved the animal glue manufacturing facility to a custom-built site in Monroe, North Carolina.  This site has been expanded upon multiple times as business has called for it.

Recent Years

In 2000, Louis “Tripp” Davis III took over the company when his father retired.  Since then, we have expanded our distribution services and are a major distributor for HB Fuller and Ashland Chemical products.  This enables us to provide our customers with hot melt adhesives, PUR glues, and fugitive glues that we do not manufacture.  LD Davis manufactures eco-adhesives which are animal glue and liquid glues.

85 holiday seasons is a huge accomplishment for our company.  We are proud to have served our customers for this long and look forward to many more years, and holidays, of quality adhesive manufacturing.

We wish Happy Holidays and a great start to 2012 to all of you!

Don’t Forget!

We would love to hear from you. Please comment on this blog or communicate with us via Facebook, Twitter, YouTube, LinkedIn and Google+

 
Happy Holidays

Happy Holidays from LD Davis

Animal Glue Raw Materials

Posted on December 8th, 2011 by L.D. Davis Industries, Inc

LD Davis has been manufacturing animal glue, also known as hide glue or protein adhesive for eight decades in the United States.  Animal glue comes in cake form and is melted prior to use at different temperatures depending on the application.  This glue is considered to be an eco-adhesive because it is totally non-toxic and biodegradable.  This is possible because of the raw materials used to manufacture this glue.

Animal glue raw materials are as follows:

Gelatin:

  • Prior to 1970, mostly extracted from the bones and hides of pigs and cattle.
  • Since 1970, a good amount comes from pharmaceutical scrap gelatin
  • Soft gel netting and hard capsule gelatin are both used in glue manufacturing
  • Soft capsule gelatin is sorted by color before use in animal glue manufacture.
  • Further helps the environment by recycling pharmaceutical scrap that would otherwise be thrown in landfills.

Water:

  • Animal glue is technically a water-based adhesive
  • LD Davis only manufactures water-based adhesives, whether they are animal glue or liquid glue.

Epsom Salts:

    Also known as magnesium sulfate- made up of magnesium, sulfur, and oxygen.
  • Epsom salts are also used in agriculture, medical applications, bath salts, and even in some food processing.
  • Epsom salts are used in animal glue manufacture to add tackiness to the formula.

Corn Sugars:

  • Used in animal glue production for additional open time and wet tack.
  • Derived from corn starch
  • All natural sugar used in animal glue production
  • Increases eco-friendliness because it is a renewable resource

Glycerin:

  • Used in animal glue production to add flexibility and non-warp properties.
  • Colorless and odorless
  • Used in pharmaceutical applications, is usually an ingredient found in soaps.
  • Can be used as a food preservative and is often found in products like butter and margarine.

Water-Based Adhesives and Food Packaging

Posted on August 18th, 2011 by L.D. Davis Industries, Inc

In the July/August 2011 issue of Folding Carton Industry magazine, an article regarding safety standards for food packaging caught my eye. L.D. Davis sells three kinds of adhesives that are used in packaging. We manufacture liquid water-based adhesives, and hide glue, or protein adhesive, and we are a distributor of H.B. Fuller’s hot melt adhesives. Both our liquid and animal glues are technically water-based adhesives.

L.D. Davis Water Based Adhesives in Packaging

Folding Carton Industry‘s article discussed how food packaging must not compromise or contaminate the food contents in any way. The substrate material, ink, and adhesive must have a miniscule to no effect on the food. All packaging materials must be safe to come into contact with the food, and our water-based adhesives are, because they’re totally non-toxic.
The water-based adhesives that L.D. Davis manufactures for food packaging are water-soluble and environmentally-friendly. Both liquid, water-based adhesive and animal glue biodegrade quickly when introduced to the natural environment and, in food packaging, present no threat of contaminating the food inside the package.
According to the article, in good food package manufacturing the food should never come into contact with the side of the package that has ink printed on it. If packaging labels are stacked on top of each other or on a roll, small, invisible ink particles may attach to the non-printed side of the packaging and come into contact with the food. Packaging adhesives should also generally not come into contact with the food, but L.D. Davis water-based adhesives and animal glues are non-toxic, so they will not contaminate the food if they do come into contact.

Components of Water-Based Adhesives

While we definitely don’t recommend snacking on our glue, if you really wanted to, you could. However, we all got our paste-eating habits our of our systems in kindergarten :) L.D. Davis animal glues, which are water-based adhesives, are made from the same edible gelatin used to make gel caps and other pills by pharmaceutical and nutritional companies. Pharmaceutical-grade gelatin is used in these types of pills, while food-grade gelatin is used in popular candy like gummy bears and snacks like Jell-O.

Safe, Green, Eco Adhesives

L.D. Davis is North America’s premier and largest protein adhesive compounder. Our water-based adhesives are totally non-toxic and environmentally-friendly. We provide the food packaging industry with our Green Advantage, which comes from a long history of manufacturing green, non-toxic, water-based adhesives. While the food packaging industry delves into safety regulations for terms of inks and substrates, they can rest assured that L.D. Davis packaging adhesives will certainly not contaminate the food inside the package. Our water-based adhesives are an asset to the food packaging industry because they are non-toxic, biodegradable, and certainly comply with food packaging safety regulations detailed in the recent Folding Carton Industry magazine article.
