What Are Coroplast Plastic Sheets?
Coroplast is the generic trade name commonly used to refer to corrugated plastic sheeting. It’s basically waterproof cardboard.
Coroplast is made of polypropylene and has a solid outside layer on both sides with a hollow, ribbed core in the middle. The construction of these three layers is what makes coroplast so versatile for ecommerce consumers. You will find sheets of coroplast that are:
- Lightweight
- Waterproof
- Impact resistant
- Reusable
- Easy to cut and shape
Essentially, coroplast can do anything cardboard can…except degrade upon contact with moisture or compressive forces.
Most bulk orders, or orders that require custom sizing, will come directly from this supplier of corrugated plastic sheeting. That’s because big-box home improvement stores don’t carry nearly as many thickness options, colors, or sheet sizes. Purchasing from them directly is typically more affordable as well…. and you have way better quality control.
Why Ecommerce Demand For Coroplast Is Growing
The demand for coroplast plastic sheets isn’t just holding steady. It’s climbing fast.
Here’s why:
E-commerce continues to rise. Each and every order that ships requires protective packaging or dividers of some sort. More brands are transitioning from cardboard to corrugated plastic as it lasts longer.
Did you know: In 20 24 there were 85 million damaged deliveries, which is 30% higher compared to previous year. This is a MASSIVE problem for eCommerce sellers.
Another reason more of them are moving to more durable packaging options like coroplast.
Even market research supports this fact. According to Market Research, the U.S. corrugated plastic sheets market size reached $177.9 million in 20 24; It is expected to continue rising annually through 20 33.
So what does this mean for ecommerce shoppers?
- More suppliers to choose from
- More competitive pricing
- A bigger variety of sizes and colours
- Better shipping options
Pretty cool, right?
Common Uses For Coroplast
Can’t decide if coroplast plastic sheets are what you need? Here are the most popular reasons ecommerce customers purchase them for:
- Signage: Yard signs, real estate signs, political signs, event signs
- Packaging: Dividers, protective inserts, reusable shipping totes
- Craft projects: School projects, DIY builds, model making
- Storage: Pet trays, garden boxes, plant protection
- Industrial: Floor protection, wall guards, temporary barriers
Cheap and durable, coroplast is usually the default plastic sheet that people reach for when they need something sturdy — and don’t want to break the bank.
How To Pick The Right Coroplast Sheet
This is what trips up most ecommerce shoppers. Coroplast sheets come in many different sizes.
To pick the right one, focus on three main things.
Thickness
Thickness is measured in millimetres. Most coroplast plastic sheets come in these ranges:
- 2mm–3mm: Best for lightweight jobs like signs and craft projects
- 4mm–5mm: The most popular thickness — great for most signage and packaging
- 6mm–10mm: Heavy-duty use like floor protection or industrial partitions
Still not sure what thickness you should choose? Go with 4mm. It’ll work fine for most applications.
Sheet Size
Sheet sizes can vary a lot from supplier to supplier. Standard sizes include:
- 24″ x 36″
- 48″ x 96″
- 40″ x 60″
Most suppliers also offer custom sizes if you’re buying enough. Just keep in mind — larger sheets are more expensive to ship. Consider this when browsing before you buy.
Colour
Coroplast plastic sheets are available in all colours of the rainbow. Popular choices are white, black, yellow, red, blue and green.
Colour choice is typically dictated by the project. Signs usually require bright colours to stand out. Packaging projects often use simple white or black.
Buying Tips For Ecommerce Shoppers
Now for the fun part.
Follow these tips to ensure you save money when shopping online for coroplast plastic sheets.
Buy In Bulk
The bigger the order, the lower the price per sheet.
Assuming you have storage space for the additional rolls, purchasing bulk will almost always save you money down the road. Some vendors will even offer free shipping when you order a certain quantity.
Check Shipping Costs Carefully
Coroplast is lightweight… but the sheets are big.
That is why sometimes shipping costs more than the sheets! Remember to look at shipping before checkout!
Read The Product Specs
Not all coroplast is created equal. Look for things like:
- UV resistance
- Weight per square metre
- Material type (polypropylene is the standard)
- Flute direction
Ordering blindly is how many customers become unhappy with their purchase.
Compare Suppliers
Prices between suppliers can differ hugely. Really does pay to shop around at least three before deciding. Consider:
- Prices
- Sheet sizes
- Minimum order quantities
- Shipping fees
Order A Sample First
Planning a big order? Always ask for a sample sheet first.
That way you can test the quality before ordering hundreds of sheets. Most legitimate suppliers will send you samples for a small fee (sometimes even free).
Bringing It All Together
Coroplast plastic sheets are easily one of the most useful purchases you can make as an ecommerce consumer. Affordable, durable, waterproof, and simple to work with.
For signs, packaging or just DIY stuff… coroplast is ALWAYS going to be a good choice.
Just remember to:
- Pick the right thickness for the job
- Check the sheet size before ordering
- Compare a few suppliers before buying
- Read the product specs carefully
- Ask for a sample first if it’s a big order
Do this and the coroplast plastic sheets that arrive at your door will be precisely what you need … for free!
Happy shopping
