McKinsey Takes a Look at the Future of Packaging

Future of Packaging

McKinsey and Co. recently put out a series of online articles that explore the future of packaging.  We thought we’d highlight a couple of them for you here today.

McKinsey Interviews WestRock CEO on the Future of Packaging

McKinsey’s Nick Santhanam recently spoke with WestRock CEO Steve Voorhees to gain his perspective on the packaging sector and the road ahead.

In the interview, Voorhees reflects on the three primary roles that packaging serves (protecting, promoting, and performing) and shares his belief that the biggest changes have come in the form of performance, which will continue to be the case over the next five to ten years.

Why has performance led the pack?

  • For one, he credits sustainability (like paper-based packaging) because it’s made from renewable and recyclable resources that consumers prefer.

  • For another, it relates to new technologies embedded in packaging that allow it to do more than just protect products. For instance, the introduction of innovations like the “19 Crimes” wine bottle labels, which animate when used in combination with a smart phone app.

  • And finally, he credits ongoing R&D efforts that are generating new ways to replace plastic with paper.

Smart Bottles and Edible Boxes?

And in another great packaging article from McKinsey, David Feber, Daniel Nordigården, and Nick Santhanam describe what packaging could look like in 2030.

  • Milk jugs with sensors?

  • Personalized wine bottles?

  • Edible boxes and bags?

These are just a few examples of The Next Normal in packaging. To see the full McKinsey article, click here.

Seven Things to Consider When Determining Bonding Requirements

bonding

When considering bonding and sealant options, answering a few simple questions can help guide you to the right solution.

1.  What Are You Joining Together?

Is it a sub-assembly or a finished part, and is disassembly a consideration?  Also, does it require bonding (e.g. adhesive) or joint filling (e.g. sealant)?

2. Substrates?

What substrates are you connecting, and are those materials rigid, flexible, smooth, rough, non-porous, or treated?  And if the substrate turns out to be treated, with what?  Finally, does your adhesive need to be stronger than the substrate itself?

3. Design Joint?

Is your design joint going to be under high stress, dynamic load, or static load?

4. Application?

Will you be applying your adhesive or sealant manually, or assisted by either a machine and/or a fully automated process?

5. Curing?

How do you intend to cure your adhesive or sealant?  For example, will it be by heat, or moisture, or UV light, or electron beam light, etc.?  Also, what is the service temperature range that will be needed when applying your adhesive or sealant (whether continuously or intermittent)?

6. Resistance?

Is there anything your adhesive or sealant needs to resist, like moisture, or immersion, or weathering, or sunlight, and more?

7. Standards?

And finally, do you need to comply with standards like UL, US FDA, etc.?

What are Pressure-Sensitive Adhesives?

pressure-sensitive adhesives

Industrial adhesives are typically organized by either their reactiveness properties (whether it chemically reacts in order to harden), or by its origin (natural or synthetic.)

In the reactiveness category, one of the world’s most popular bonding solutions is the pressure sensitive adhesive or PSA.

So, what is a Pressure-Sensitive Adhesive?

Pressure-sensitive adhesives are designed to form a bond by the application of light “pressure ” to marry the PSA with whatever needs to be adhered together.

Why use a Pressure Sensitive Adhesive?

For the right applications, PSAs offer a unique balance between what we call “flow” and what we call “resistance to flow.”  For example, as the bond initially forms because the adhesive is soft enough to flow (i.e., “wet”), it then strengthens because the PSA is hard enough to “resist flow” when stress is applied to the bond.

Once the PSA and the elements to be adhered are in close proximity, molecular interactions become involved in the bond, contributing significantly to its ultimate strength.

Pressure-Sensitive Adhesive Applications

PSAs are typically designed for either permanent or removable applications.

Examples of some permanent applications include:

  • Safety labels for power equipment

  • Foil tape for HVAC duct work

  • Automotive interior trim assembly

  • Sound/vibration damping films

Examples of some removable adhesives applications include:

  • Surface protection films

  • Masking tapes

  • Bookmark and note papers

  • Barcodes labels

  • Price marking labels

  • Promotional graphics materials

  • Skin contact (e.g. wound care dressings, EKG electrodes, athletic tape, etc.)

Pressure-Sensitive Adhesive Manufacturing Process

Most PSAs are manufactured with either a liquid carrier or in 100% solid form.

  • Articles are made from liquid PSAs by coating the adhesive and drying off the solvent or water carrier. They may be further heated to initiate a cross-linking reaction and increase molecular weight.

  • 100% solid PSAs may be low viscosity polymers that are coated and then reacted with radiation to increase molecular weight and form the adhesive, or they may be high viscosity materials that are heated to reduce viscosity enough to allow coating, and then cooled to their final form.

  • Major raw material for PSA’s are acrylate-based polymers.

Advantages of Industrial Hot Melt Adhesives

Box of Hot Melt Glue

 

If your daily conversations include phrases like “open time”, “set time”, “tack”, and “surface energy”, your job probably involves some form of hot melt adhesive, or HMA.

Popular among hobbyists for use in crafting projects (think of those glue sticks used in glue guns), it is even more popular in industrial applications as an alternative to water-based adhesives.   

These advantages include:

  • Reduction or elimination of volatile organic compounds

  • Elimination of the drying or curing step

  • Long shelf life

  • Disposable without specific precautions

  • No loss of thickness during solidification

  • Lower shipping costs and greater transportation distances

Flexibility

Hot melt adhesives offer increased flexibility in areas like “open time”, where the working time it takes to make a bond can range from just seconds for fast-setting HMAs, to infinity for pressure-sensitive adhesives (PSAs).

Versatility

Hot melt adhesives offer versatility in the array of different substrates that they can bond with, including rubbers, ceramics, metals, paper, plastics, glass and wood.

Variety

Industrial HMAs come in a variety of different types, including larger sticks and glue guns with higher melting rates, as well as in granular or power hot melt blocks for bulk melt processors.

Applicability

Here are just a few of the many examples where different applications and industries take advantage of the benefits of HMAs:

  • Corrugated boxes and paperboard cartons in the packaging industry

  • Disposable diapers in the hygiene industry

  • Spine gluing in the bookbinding industry

  • Affixed parts and wires in the electronics industry

  • Product assembly and lamination in the woodworking industry

Of course, hot melt adhesives may not always be the best option.  These can include use on substrates that are sensitive to higher temperatures, as well as end-products that can be exposed to higher temperatures, chemicals, or weather conditions where an HMA may offer less bond strength or resistance.

For these reasons and others, Evans proudly offers packaging hot melt adhesives, pressure sensitive hot melt adhesives, and water-based adhesives to our industrial customers.  Whatever your requirements call for, Evans manufacturing and research teams are here to help.

A Brief (200,000) Year History of Adhesives

history - colosseum

The year is 2019, and at Evans Adhesive we know that our heritage of sticking things together goes way back.

But how far back might surprise you…

200,000 Years Ago

The earliest use of adhesives is discovered in central Italy when two stone flakes partially covered with birch-bark tar and a third uncovered stone from the Middle Pleistocene era were found.

70,000 Years Ago

The first use of compound adhesives is discovered in Sibudu, South Africa. Stone segments that were once inserted in axe hafts were discovered covered with an adhesive composed of plant gum and red ochre to prevent disintegrating under wet conditions.

6,000 Years Ago

Tribesmen had buried their dead together with food found in broken clay pots repaired with tree resins.

5,200 Years Ago

Pitch, which require heating of tar during its production, used to connect the stone or metal parts of spear and copper hatchet to the wooden shafts.

4,000 Years Ago

The use of bituminous cements to fasten ivory eyeballs to statues in Babylonian temples.

2,000 Years Ago

Romans began using pozzolanic cement in the construction of the Roman Colosseum and Pantheon.  Greeks began the use of slaked lime as mortar, while Egyptian paintings depict wood gluing operations and a casket made of wood and glue in tombs.

1,000 Years Ago

Mongols construct bows with laminated lemonwood and bullhorn bonded by an unknown adhesive.

500 Years Ago

World-renowned cabinet and furniture makers such as Thomas Chippendale and Duncan Phyfe began to use adhesives to hold their products together.

329 Years Ago

The development of modern adhesives began in 1690 with the founding of the first commercial glue plant in Holland. This plant produced glues from animal hides.

269 Years Ago

In 1750, the first British glue patent was issued for fish glue. The following decades of the next century witnessed the manufacture of casein glues in German and Swiss factories.

189 Years Ago

Natural rubber was first used as material for adhesives starting in 1830.

172 Years Ago

The first US postage stamps used starch-based adhesives when issued in 1847.

152 Years Ago

The first US patent (number 61,991) on dextrin (a starch derivative) adhesive was issued in 1867.

143 Years Ago

 In 1876, the first US patent (number 183,024) was issued to the Ross brothers for the production of casein glue.

106 Years Ago

The pressure-sensitive tape industry is born.   Today, sticky notes, Scotch tape, and other tapes are examples of PSA (pressure sensitive adhesives.)

108 Years Ago

By 1927, solvent-based thermoplastic rubber cements for metal to rubber bonding come into vogue.  Two World Wars in the 20th Century would also push advances in the development and production of new plastics and resins even further.

Adhesives and High Performance

high performance

 

Achieving high performance is a crucial — and perhaps obvious — end goal in all manufacturing circumstances. No matter what product you are manufacturing, you want it to perform at the highest possible level.

The fastening method you choose when assembling your product can play a big role in the final performance of your finished product. From small items like hinges and gaskets to huge parts of complicated systems like airplane wings, adhesive can offer performance improvements that are difficult or even impossible to achieve with non-adhesive fastening methods.

Here are two ways in which using adhesives can offer peak performance

1) Adhesives allow the use of high strength, low weight materials

Traditional fastening methods like rivets, screws and welding are excellent for joining high strength, high weight materials together. In a situation that calls for the use of heavy weight metals or wood, these methods are perfectly fine.

But those materials are not available or even advisable for all applications. In aerospace engineering, for example, using these materials would be highly impractical.

Using adhesives as the fastening method in these applications allows for the use of high-performance plastics and laminates, ideal materials for a situation where both strength and weight are a premium.

2) Adhesives limit the drawbacks of other fastening options

Non-adhesive fastening options also bring certain drawbacks.

No matter the material used in your application, welding can introduce weakening. Even when taking steps to reduce the affects, some heat-induced weakening is inevitable. The same is true for riveting or screwing, which introduces stress weakening to the fastening area. Adhesives are a straightforward solution to these problems, allowing for fastening without weakening due to heat or stress.

Non-adhesive fastening methods also add weight to your finished product, but that’s not the case with adhesives. A continuous line bond in adhesive fastening eliminates weight common to other fastening methods while providing uniform adhesion across a broad surface, adding strength and increasing durability.

Adhesives Improve Appearance, Durability and Reliability

adhesive durability and reliability

The internal benefits of adhesives are clear: using adhesives as your fastening solution allows for more flexibility in production and in applications and may make you more productive. But adhesives also have significant benefits for your end users as well. Products that utilize adhesives can have significantly higher quality, durability and reliability than those that use other fastening methods.

Adhesives allow for a better look and feel

A product’s quality is largely subjective, but not entirely. Consumers regularly show preference for some products over others for a variety of reasons.

Aesthetic appeal is one such reason. Using adhesives can be a significant benefit to the final appearance of your product, eliminating unwanted visible joint lines and allowing products to retain their shape without shrinkage or other material degradation. These characteristics are especially useful in clothing manufacturing.

Adhesives can also eliminate the corrosion and other material decline associated with metal fasteners or other materials used as fastening solutions. Over time, this corrosion can reduce the quality of adhesion and stain or discolor the surrounding area, leaving an aesthetically less-satisfying product in its wake.

Adhesives increase durability and reliability in every situation

In addition to looking better, products created with adhesives offer greater durability and reliability than those with mechanical fasteners.

An adhesive seal spreads and absorbs stress to a far greater degree than any other fastener. More than any other fastening method, adhesives spread and absorb stress at the point of fastening, increasing fatigue resistance and evenly distributing the load across the entire bond.

Adhesives can also create hermetic seals against moisture, smoke and fire, UV light and environmental contaminants of all types while solidly securing the various parts of your product together. Products created with adhesives, therefore, can be counted upon to perform at a high level in just about every situation, no matter the environmental factors.
