Flexible packaging combines the best qualities of plastics and films. These versatile packaging supplies are a functional solution that requires minimal production costs.

 

Flexible packaging is any package or any part of a package whose shape can be readily changed.” Common examples of flexible packaging include bags, pouches, shrink films, tubes, sleeves, and carded packaging.

 

In this article, we detail why flexible packaging is so beneficial. And, we also outline considerations for purchasing flexible packaging for your products.

 

 

Why Use Flexible Packaging?

 

Flexible packaging is a solution that businesses turn to for a variety of reasons. For starters, it’s less expensive than rigid packaging. But, it also offers excellent durability and product protection. Polyolefin shrink films are a popular high-quality material. These films are approved by the FDA to increase shelf life.

 

The quality of flexible packaging isn’t its only calling card, however. It’s also touted for its ability to be tailored to fit the specifics of any product. It’s possible to package products of many shapes and sizes with flexible packaging. And, you can do this with an array of materials.

 

That is good news for businesses creating packages that help sell their products. With flexible packaging, companies can think outside of the box to engage consumers.

 

Speaking of consumers, flexible packaging helps designers create attractive packages. These packages are more convenient for consumers. Additionally, flexible packaging is a form of sustainable packaging. These alternatives include cardboard, glass, and other types of rigid packaging.

Flexible Packaging Material Options

 

There are many different options for flexible packaging materials. For the sake of brevity, we’ll limit our list to the most popular items.

 

Keep in mind that working with a packaging partner will help you select the best packaging. When you use the ideal solutions, you’ll save time and money in the long run.


Stand Up Pouches

 

One of the best alternatives to traditional packaging is stand-up pouches. They function as their name suggests – standing upright on shelves. This packaging has an airtight closure.

 

Stand-up pouches (also known as flexible pouches) are extremely easy to pack, and they have incredible branding capabilities through digital printing. Stand-up pouches can be custom printed with eye-catching graphics and breathtaking colors.

 

 

Stand-up pouches are fully customizable to your needs. And stand-up pouches have multiple barrier layers of protection. They can suit nearly any product, many of which are listed in the flexible films section below.

 

Flexible Films

 

As you can already tell, there are many different flexible film materials. Here are 14 of the most popular:

 

  • (EAA) Ethylene Acrylic Acid

    – A tie layer between aluminum foil and other polymers.

  • (EVA) Ethylene Vinyl Acetate

    – An adhesive layer, moisture barrier, and heat-sealable food contact layer.

  • (EVOH) Ethylene Vinyl Alcohol

    – An oxygen barrier typically placed between PE/PP films, EVOH must be protected from moisture.

  • (PA) Polyamide

    – A film that works well as an outer layer, PA provides machinability, a gas/aroma barrier, heat resistance, and will not stick to a sealer bar.

  • (PC) Polycarbonate

    – A moisture and heat-resistant barrier with machinability.

  • (PE) Polyethylene

    – Another heat-sealable food contact layer, as well as a moisture barrier. It can also be combined with gas/aroma barriers such as (EVOH, PA).

  • (PEN) Polyethylene Naphthalate

    – A gas/aroma barrier with machinability and heat resistance.

  • (PET) Polyethylene Terephthalate

    – A film that provides machinability strength, PET is all of a gas/aroma barrier, moisture barrier, and heat-resistant.

  • (PET-G) Glycol-Modified Polyethylene Terephthalate

    – A heat-sealable food contact layer.

  • (POF) Cross-Linked Polyolefin

    – A heat-sealable film best suited for food packaging but also used to laminate print products. Made using a cross-direction technique in which film is stretched both mechanically and manually.

  • (PP) Polypropylene

    – A moisture barrier that can be combined with other gas/aroma barriers or coated with heat-seal coatings such as acrylate and PVDC.

  • (PS) Polystyrene

    – A printable and gas-permeable film that can be combined with other gas/aroma barriers.

  • (PVDC) Polyvinylidene Chloride

    – An O2 barrier and heat-sealable layer that provides gloss and protects print.

  • (PVC) Polyvinyl Chloride

    – A gas/aroma barrier with machinability.

 

Foil Packaging

 

Foils are used mainly by the food and pharmaceutical industries. Foil packaging keeps food fresh. And, it keeps food safe by blocking contaminants, increasing your products’ shelf life. It is also a recyclable material.

 

Additional Protective Packaging

 

Flexible packaging materials range in type and size. They can be designed for all kinds of packaging needs – from small products to large equipment. Flexible packaging can also be used to palletize bulk products.

 

Air pillows are a great example of lightweight and secure protective packaging. They protect products from shock and vibration. They do this during transit.

 

Air Pillow Machine

 

Air pillows are easy to recycle and dispose of. This is especially true when compared to messy packing peanuts. Electrostatic discharge (ESD) bagging is especially great for packaging sensitive electronics. This is done to avoid damage due to static and friction.

 

How Do You Know If You’ve Chosen The Ideal Flexible Packaging?

 

Is your goal to increase your product’s shelf life? Do you want to minimize product loss during transit? You can’t know if you’ve chosen the right solution until you’ve defined all of your requirements. You need some parameters to give you a direction.

 

In terms of protection, you’ll also need to define what your products need protection from. Do you have a long shipping process with many risks for error?

 

Will your product be delivered to a location at a high altitude? Does the area have high humidity or low temperatures? These considerations all impact what packaging is the optimal solution.

 

You’ll also need to set your budget, but don’t make the mistake of being too short-sighted. Beyond cost, you must consider whether you’ll need to set up new packaging machinery (for example, form fill and seal machinery).

 

And, you may need to add secondary packaging to maintain the safety of your product. As early as possible, communicate with your suppliers, aware of your budget. Discuss any financial constraints. This will help you save time in the material selection process.

 

Speaking of which, you’ll need to budget time for review and modifications. Don’t expect quick fixes to be cost-effective. Give yourself time to review your flexible packaging.

Buyer's guide: Frame protection for road and gravel bikes

Frame protection generally takes the form of special clear tape applied to areas of your bike likely to suffer wear or impacts.
This can be for vanity’s sake, guarding against chips and scuffs while helping you preserve your bike’s resale value. At the same time, it can also help prevent more severe damage such as that caused by rock strikes or your bike taking a tumble.
Anyone who’s heard the thwack of a rock shooting up from the ground to connect with their down tube will understand why you might want to add some extra protection, particularly useful on carbon frames.

Gravel bikes in particular benefit from additional frame protection given the kind of terrain they’re aimed at. The same goes for any carbon frame that’s likely to be used in the mud or to which you might attach bikepacking bags – bag straps are particularly good at wearing through your finish.

Do I need frame protection for my bike?

Protection serves two purposes. First, it stops scuffs and scratches, like those caused by repeated rubbing or your bike sliding or knocking against something. This kind of wear can also result from your frame being regularly clamped into a work stand or bike rack, or having bags or straps lashed around its tubes.
Secondly, thicker and more absorbent tapes can also prevent structural damage. This sort of impact might result from a rock striking the down tube, an accident like dropping something onto the top tube, or a crash.
Carbon bikes tend to be more at risk of structural damage than aluminium models, whereas steel bikes are almost impervious to the kind of damage frame protection tapes can guard against, although they’ll still benefit from protection to their finish in key areas.

How does frame protection for road and gravel bikes work?

Despite being made for the outdoors, many road and gravel bikes aren’t really designed for a knockabout life. While the layups of more robust carbon bikes generally include additional layers of fibre designed specifically to disperse surface impacts, racier machines which focus on minimal weight often do without.
So while frames are extremely strong in the directions needed for stiffness, even a relatively small impact can cause a crack. Helping absorb and disperse impacts, frame protection tape can potentially prevent structural damage while helping you shrug off cosmetic damage.
Of course, this style of frame protection isn’t anywhere near failsafe. Still, given its popularity among mountain bikers, you can bet it’s saved more than a few riders from heartache.
Most frame protection kits use a material similar to 3M’s 8671HS ‘helicopter tape’. This soft polyurethane tape can be wet-applied to your bike frame and feels almost tacky to the touch.
Visually obvious if you look closely, such kits will add between 40-120g once applied to the frame. Thinner and less obvious-looking styles of tape are also available, although these will offer less in the way of structural protection.
While both types will generally stick to matt paint or raw aluminium, they’re usually incompatible with anodized frame finishes.

2. Invisiframe Frame Protection

  • Price: £80-85 for model-specific kits

Invisiframe is unusual in producing specific kits covering popular road, gravel, and cyclocross bikes.
With pre-cut shapes matched precisely to your frame size, these are likely to be your best option if your bike is covered.
Alternatively, the firm offers generic kits. Exact dimensions are included on the website, but expect a degree of modification to be necessary to achieve the perfect match.

3. All Mountain Style Gravel/Road Frame Guard

  • Price: €43

With a dimpled, honeycomb surface texture, All Mountain Style’s tape kits are thick while still maintaining a low weight and enough flexibility to make them conform to the shape of your frame.
The brand offers a single kit for road or gravel bikes, which comes in a clear semi-matt finish or with two different graphic treatments.
Made up of 12 parts, this includes big swatches for the top tube and down tube, two long arrows for the fork or the seatstays, plus eight extra sections to guard against cable rub or protect areas where the tyre might contact the frame.
More noticeable than some films, it helps that the tape itself looks good. This kit isn’t too expensive and is likely to provide better-than-average impact protection.

4. Ride Wrap Bike Protection

  • Price: from £30

With a vast range of options, Ride wrap offers custom-tailored kits and several generic options. Currently a little light on model-specific road and gravel kits, its online tool does at least help you find the best fit from among its other products. The firm also offers individual kits for those wanting to protect just their fork.
Likely to require a little trimming, its £60 ‘Covered’ kit should offer around 60% coverage, while its £30 ‘Essential’ kit concentrates on the most critical areas, including the top tube, down tube, seatstays and chainstays.
Arriving with each kit is a squeegee, cleaning wipes, installation solution concentrate, microfiber cloth, and an install key tool. A boon for anyone who doesn’t happen to have such things lying around already, they should offer a good value package.

5. Bike Shield Oversize Frame Protector Set

  • Price: £37.99

The frame protection product most likely to already be hanging up in your local bike shop, Bike Shield kits come in versions for standard or oversized frames.
Matt or gloss finishes are available, and you can buy complete kits or single strips to cover your top tube, down tube, or chainstay.
Made from self-healing material, this tape is easy to fit and not too expensive. Most patches are rectilinear, so it is easy to work out where to place them, although you won’t get the same extended coverage offered by more complex kits.
Despite not being as thick as some alternatives, it should still provide a degree of impact protection and is easily tough enough for cosmetic duties.

  • Buy Now from Amazon for £37.99

6. Lizard Skins Frame Protection Kit

  • Price: £42

These Frame Protectors from Lizard Skins are available as a kit or a single strip to protect an individual tube, and both are simple to select and widely available.
Strips are cut to conform to curving tube profiles, and each also features supplementary chevrons, which can be used to extend their length, while if you opt for a complete kit, you’ll find some extra patches chucked in too.
This means it’s less likely you’ll need to cut them, and you should be able to achieve a neat fit without much hassle. The flip side is that you’ll be restricted to just the main stretches of tubing on your bike.
Relatively thick, it’s confidence-inspiring stuff, although anyone wanting maximum coverage would still be best to look elsewhere.
