How to choose a suitable double wall box?
In order to avoid the loss of product damage, choose the suitable double wall carton box is so important, aimed at so many kinds of double-layer carton box, how to choose the one that fits you? Don’t worry, after 2 minutes you will find your answer.
1.What’s the difference between single wall and double wall boxes?
First, we should know that single wall box is designed for lighter goods than carton box double wall, such as the e-commerce industry, while double-wall long cardboard boxes are commonly used for heavy-duty goods, such as furniture.

Material: B flute
Box type: Normal
Second, just as the name showed, though these two boxes are made of fluted paper sheet sandwiched between two sheets of liner paper, the single wall box is designed with only one flute layer, and most often, the fluted layer of a single wall box is larger than double layer cardboard boxes to absorb more shock and offer more protection, and double-sided cardboard boxes hold 5 ply construction that contains 2 flute layers and 3 paper layer, that’s why the double-wall box can carry more weight, on the contrary of single wall box, the flute of cardboard box double wall are short.
Usually, we will use kraft paper on the outer layers, while test paper on the inner paper, just about the paper and flute layer to ensure the rigidity and strength of boxes.

Third, the flute materials are also different for single wall boxes and double-walled cardboard boxes. Generally speaking, the A, B, C, and E flutes are mainly for single wall boxes, and sometimes we also called the E flute as micro flute, which mainly used for home appliances, while the B and C flute usually used for cardboard double wall boxes, and the combination of AB flute, CB flute, BE flute also used for double wall cardboard boxes eBay, AB, and CB flute mainly for refrigerator, air conditioner, television, and computer packaging, which hold great cushioning so that can protect your product the greatest extent. One point we should know, the A flute is the thickest than other types of flutes, it can’t afford heavy-duty items, that’s why it’s used for single wall boxes in most instances.

2. What’s the difference between double-wall cardboard boxes and double wall corrugated boxes?
First, you should know that no matter the single wall box or large double wall cardboard boxes, there can be divided into almost 3 types according to the used materials, they are cardboard box, corrugated box, and carton box, of course, these 3 are not the whole story, however, they represent most.
As mentioned above, the cheap double wall corrugated cardboard boxes are grouped into 5 layers that include 2 flute layers and 3 paper layers, these structures and materials depend on the strength and rigidity of double strength cardboard boxes, however, the double-wall cardboard boxes aren’t necessary 5 layers, maybe 5, 4 or 6 layers, it depends on which good you want to ship, the biggest difference between extra-large double walled cardboard boxes and cardboard boxes is the fluted layer, the cardboard boxes use several paper layers in the middle instead of flute layers.
Besides, as a rule, sturdy double wall corrugated boxes are larger than double wall cardboard boxes, so there can’t comparison of their price intuitively, however, at the same size, double wall corrugated boxes are cheaper than double wall cardboard boxes.
How to Choose The Right Moving Double Walled Boxes
1.Materials and Styles of Moving Double Wall Box
Most of the time, the main raw material for moving heavy-duty double wall boxes is raw wood pulp, there are regular and hard materials. For short distance moving, these general double-walled dish pack boxes are suitable, while for long-distance handling, because of the need for multiple handling, so hard material is your best choice.
At present, all Shie’s double-wall shipping boxes are made of hard material, which is strong enough to bear a certain weight for a long time.
If the move double-wall packing boxes need to store books and other hard items, you can choose to buckle hands, so convenient both hands can pick up the boxes.
If the goods stored are heavy, you can choose to directly lift double-wall postal boxes without the buckle hand, because the high bearing capacity may cause the boxes with the buckle hand to fall apart.
2.Sizes of Move Double Walled Boxes
Usually, there are 3 sorts of specifications of double wall board boxes in Shie, and each has its suitable items.
1.50x40x35
This specification of the move double wall boxes near me are suitable for books and other daily sundry items, which can hold about 20 bags of A4 paper, so they are especially suitable for file information.
2.60x40x50
These kinds of moving twin wall boxes are mainly designed for lightweight contents, such as clothes, shoes, toys, or some relatively light small household appliances and other items. Almost one double-walled box near me can hold about 50 pieces of clothing and a desktop computer, In a word, this specification double-walled corrugated boxes are commonly for daily necessities. If need to pack for fast shipping, the double-walled moving boxes of the charge by weight are also advantageous.
3.80x50x60
This specification of moving double box is mainly suitable for more bulky items, such as putting quilt, pillow, winter wear down jacket, or plush toys.
Specifications:

One 80x50x60 double wall box can contain 2 thick quilts or 20 down jackets. These double-walled boxes aren’t fit for too heavy scattered items, otherwise may leading to the uneven bearing of the boxes and are not easy to move.
Tips: After moving, disconnect the tape and store these double corrugated boxes, and we can use them again.
Inspection Standard of Double Walled Boxes in Shie
In order to offer you first-class double wall corrugated boxes, Shie developed a set of standard testing procedures just as follows.
1.Appearance Quality
1. Printing Quality: First, we will ensure that the patterns and handwriting are printed clearly, with consistent and bright colors. Second, printing position error should not exceed 7mm for large double corrugated and 4mm for small boxes.
2.Sealing Quality: There is no loophole around the double-wall corrugated box, at the same time, also without irregular and open joint when the box cover.
3.Dimensional Tolerance: The tolerance between the inner diameter of the box and the design size should be 5mm for the large double-walled tuck front boxes and 3mm for the small box, and the overall size should be basically the same.
4.Cover Folds Numbers: After the shake cover of the corrugated double-walled carton boxes are opened and closed 180 degrees and reciprocating folding for more than 5 times, the total crack length between the surface layer and the inner layer of the first and second types of boxes and the inner layer of the third types of boxes is not more than 70mm.
In addition, we also require that the double layer carton boxes hold canonical joint, neat edges, and no overlapping corners, as well as there isn’t obvious damage or stains on the box surface.
Compressive Strength and Influencing Factors of Double Walled Boxes
The compression strength is an important quality index for many commodity packaging requirements for double-wall carton boxes, during the test, the double-wall corrugated boxes are placed between two pressure plates, and keep pressing until the double-walled boxes collapse, then we will get the compressive strength of the double-walled boxes for sale, which is expressed by KN
1.Set Compressive Strength of Double Walled Boxes
Because the lower layer double-walled boxes bulk will suffer from the pressure of the upper carton in the process of storage and transportation, in order to ensure these wholesale double-walled boxes can’t collapse, it must have appropriate compressive strength, that’s why we require a certain compressive strength of double-wall boxes near me.
2.Calculate Boxes’ Compressive Strength According to The Raw Material
After setting a certain compressive strength for double-wall postal boxes for sale, we will choose suitable cardboard, corrugated papers to accomplish our double-wall packing boxes, and try our best to avoid the waste caused by blind production.
There are several formulas to calculate the compressive strength of double wall shipping boxes, But the Callicutt formula is more concise and practical, it is suitable for estimating the compressive strength of 0201 double wall small parcel boxes.
3. Determine The Methods for Boxes’ Compressive Strength
Due to the influence of various factors in the production process, the compressive strength of double-walled dish pack boxes produced with raw materials may not be completely consistent with the estimated results, therefore, the final method we adopt to determine the compressive strength of double-walled carton boxes is to test the carton compressive testing machine after constant temperature and humidity treatment.
For small and medium-sized factories without testing equipment, a board can be covered above the double-walled boxes, then stack the same amount of weight on the board to roughly determine whether the compressive strength of the great double-walled boxes meets the requirements.

5 Factors Affecting The Compressive Strength of Double Walled Boxes
1. Quality of Raw Materials
From kellicutt formula, we will see that base paper is the decisive factor to determine the compression strength of the first-class double-walled boxes. However, the impact of other conditions in the production process of the corrugated boards can’t be ignored, such as the amount of adhesive, coating, and composite processing.
2.Moisture
Made by the high water content of corrugated board, or long time storage in a humid environment, high-quality double-walled boxes’ compressive strength will reduce. Due to the strong water absorption of fibers, in the rainy season and when the humidity in the air is large, the moisture balance between the paper board and the atmospheric environment is very important.
3.Box Type
Box type refers to the type of double-walled box price and the size ratio of the same type of box, they have a significant effect on the compressive strength. Some double corrugated boxes are made of double-layer corrugated cardboard, and their compressive strength is obviously improved compared with that of single-layer boxes of the same specification.
Under the same conditions, the higher the box types, the worse the stability, the lower the pressure strength
4.Printing and Opening
As we all know that printing will reduce the compressive strength of the double wall corrugated boxes. For goods with breathable packaging requirements, the strength of the double wall corrugated cardboard boxes will be reduced by opening holes on the side of the carton or punching handle holes on the side of the carton.
In particular, you will find the effect is more obvious when the whole area is large and the hole is biased to one side.
5.Process Deviation
Various reasons in the process of making carton box double wall, like improper line pressing, too deep grooving, and the fragile combination will also reduce the pressure strength of double-walled boxes for sale.
Dynamic Performance Test of Double Walled Boxes
For some specific commodity packaging, such as ceramic glass products, electrical instruments, and so on, we also need to check the buffer performance of bulk double-walled boxes, that is to simulate transportation loading and unloading, vibration, drop, and other tests for these boxes.
1.Drop Test
Drop the double-wall postal boxes packing goods from the specified height according to the correct posture, and test the state of goods inside the double-wall packing boxes after a certain number drops, or the number of times the carton fell when it was damaged.
2.Incline Impact Test
Rotated the double wall shipping boxes on the pulley, and then slide down the slope at a certain height, which is similar to the emergency braking situation during transportation.
3.Vibration Test
Place the double-wall small parcel boxes on the vibrating table after packing the goods, so that they are subjected to horizontal and vertical vibration, or suffer from two-way vibration at the same time after a certain period of time, we will check the damage of goods or double-walled boxes, finally judge their quality.
4.Hexagon Drum Rotary Test
Place the double wall shipping boxes into a hexagonal rotary drum with an impact plate, and then rotate them according to the specified number of revolutions.
Both these methods above can test the quality of double-walled boxes and try our best to offer strong protection to your goods. Just send your free quote to Shie now!
