Why Use Corrugated Cardboard Boxes to Ship Items?
Corrugated cardboard boxes provide the strength and durability at an unbeatable price point, thereby making it the primary choice of shipping boxes both by consumers and shipping companies.
It is structurally made of a fluted sheet, also called as medium lined with a paper cover on each side also called as the liner. The liner or cover is most commonly made from kraft or semi-kraft paper which is comparatively thinner than the flutes. Depending on the structure of medium and liner, there are a variety of corrugated cardboard boxes. The medium is made from paper that is made using bagasse or straw. The liner paper is crumbly, whereas the medium is relatively spongy, which gives the cardboard its flexible strength. The continuous arcs also enable the weight of the object to be evenly distributed, enabling it to withstand heavy loads.
Some common reason behind using cardboard boxes are:
- It gives a gentle traction on the transporting product. It saves the product from damage during shipping, storage, and handling. Corrugated paper is not abrasive to the transported products.
- Unlike other hard boxes, corrugated boxes don’t break; although it flexes under pressure.
- Being paper material, it is easier to print handling signs and other shipping information on the corrugated cardboard box.
- It is cost-effective to produce and is recyclable.
Use high resolution inkjet systems to print labels on boxes. The paper surface contributes in absorbing the ink and making it permanent.
How to Pack Fragile Items in Cardboard Box for Shipping?
If you think simply writing ‘Fragile’ on the box is enough to ensure your items security, you are wrong! Most package handlers work at night and have to handle thousands of boxes in a short time. People do not notice the “Fragile” remark on boxes. So, it’s up to you to secure your fragile items. In case someone handles your box in an unusual way, the item comes out safe when they reach its destination.
01. Get the right size box
You should pack fragile items snugly in the package. You can’t have any room for your fragile item to toss around in the box. Although you can use a larger box with fillers in it, fillers always leave space for the object to move around. Plus, it will cost you more in shipping and handling charges. So, it’s very important to get the right size box for your fragile items. Then you should cover it with bubble wraps on all sides. If you are shipping something hollow like a set of the wine glass, use some crumpled cardboard paper inside the glass. You could also consider sending it in another box for added safety. Even better option would be to order customized package boxes for your fragile items.
02. High-Quality Box
Corrugated cardboard boxes are of various types and come in various kinds of flutes. Buying a cheap box is a really bad idea; on the other hand, a good quality box would only marginally cost more. Get a box that has multiple flutes and liners which are sturdy enough to hold your fragile items. If you are not sure what kind of box to get, simply ask for a shipping box made of B-flute, which should be enough for most fragile items.
03. Protecting Your Items Using Bubble Wrap
Sure, you can fill up the box with peanuts and other fillers, but do care to add some extra layers of bubble wrap on it. For filler, you can also use crumpled paper, which in our opinion is a much better option than loose peanuts. For added safety, you can tap the fragile object to the package itself. Use tape only to close of the package lid and don’t go overboard and wrap it so tightly that the item breaks. Repeat the process a few more time if you are carrying a large number of fragile items in one package.
04. Label the Box as Fragile
We know we have said that marking ‘Fragile’ on the box doesn’t make much difference in actual handling, but it’s standard to add a ‘Fragile’ label in the event, your item is actually fragile. You never know, someone can notice your box and the package handler takes the pain of storing your box in a secure spot. You can also add other labels such as ‘Handle with care’ and ‘This way up.’
Packaging companies mostly use internationally recognised symbols that help package handlers to take proper measures while handling cargo packages. If you wish to transport your items in a cardboard box, you can buy specific cardboard boxes with the specific handling sign you want. Most cardboard boxes already come with some standard handling signs such as ‘This way up,’ ‘keep out of the water,’ ‘fragile’ and ‘recyclable’ as the box could be recycled. So, next time you see a sign on the box, you know exactly what it is and even know the type of contents inside the box.
