Why Cardboard For Shipping Cards Is Necessary
From my experience, using cardboard for shipping cards is absolutely essential. First, it provides sturdy protection that prevents the cards from bending or getting damaged during transit. I’ve had packages arrive with warped or creased cards before, but once I switched to cardboard, those issues disappeared.
Also, cardboard acts as a reliable barrier against moisture and dirt. I’ve noticed that without this extra layer, my cards sometimes pick up smudges or slight water damage, which really affects their quality and presentation. With cardboard, my cards stay clean and crisp, just like when I packed them.
Lastly, cardboard offers a professional touch that reflects well on my business. When customers receive cards in a solid, well-packaged box, it shows I care about the product and their experience. It’s a small detail, but it makes a big difference in building trust and satisfaction.
My Buying Guides on ‘Cardboard For Shipping Cards’
When I first started shipping cards, I quickly realized how important the right cardboard is to keep my items safe. Choosing the perfect cardboard for shipping cards can make a huge difference in protecting valuable or sentimental cards during transit. Here’s what I’ve learned from my experience to help you pick the best option.
1. Understand the Types of Cardboard
From my experience, not all cardboard is created equal. The two main types I came across are corrugated cardboard and chipboard. Corrugated cardboard has a fluted layer sandwiched between two liners, providing excellent cushioning and durability, which I prefer for shipping multiple cards. Chipboard is thinner and less protective, so I usually reserve it for very light or single card shipments.
2. Consider Thickness and Strength
I found that the thickness of the cardboard directly affects how well it protects the cards. For shipping cards, I look for cardboard that is at least 1/8 inch thick or more. The strength rating, often measured in terms of burst strength or edge crush test (ECT), is also important. I choose a cardboard with higher ratings to prevent bending or crushing during shipment.
3. Size and Dimensions Matter
When buying cardboard, I always measure my cards first and then select cardboard sheets or boxes slightly larger to allow for padding or protective sleeves. Oversized cardboard can cause the cards to shift and get damaged, while too tight can cause bending. Custom-sized cardboard or pre-cut card mailers can save time and ensure a snug fit.
4. Look for Protective Features
I like cardboard with added features like moisture resistance or reinforced edges. Some cardboard for shipping cards comes with a glossy or coated finish to protect against humidity, which is especially useful if I’m shipping to humid climates. Reinforced edges or double layers add extra strength where it counts.
5. Eco-Friendly Options
Since I care about the environment, I prefer cardboard made from recycled materials or those that are recyclable themselves. Many brands offer eco-friendly cardboard without compromising on quality, so it’s a win-win for me.
6. Ease of Use and Assembly
Some cardboard comes flat and requires folding and taping, while others are pre-assembled boxes or sleeves. I usually go for pre-assembled mailers when I’m shipping a lot of cards quickly, but for occasional shipments, flat sheets work fine. Make sure the cardboard is easy to handle and seal securely.
7. Price and Quantity
I always balance quality with cost. Buying in bulk often reduces the price per piece, but I make sure not to compromise on sturdiness. Sometimes spending a bit more upfront saves money in the long run by preventing damaged shipments.
Final Thoughts
Choosing the right cardboard for shipping cards has saved me from many damaged deliveries and unhappy recipients. By considering the type, thickness, size, protective features, environmental impact, ease of use, and cost, you can find the perfect cardboard that fits your shipping needs. I hope my guide helps you ship your cards safely and confidently!
