Quality Packaging Materials For Durable Boxes

The foundation of custom boxes is the selection of quality packaging material. Material shapes how the product will be protected and presented. Your packaging is more than a covering. It is a blend of promotional and presentation tools. 

The selection of the right material ensures box durability whole handling and shipping. Specialised processes are used to enhance the stiffness and surface smoothness of custom box materials, along with resistance to moisture and unfavourable external factors. 

Customised packaging material ranges from lightweight to dense board that delivers a premium unboxing experience. Aside from this, the ongoing wave of climate consciousness also demands sustainable materials that can keep the boxes safe for the environment. As one of the top packaging material suppliers in the UK, we use the following materials to manufacture custom printed boxes:

Kraft Paper

It’s one of the widely used materials in the manufacturing of customised boxes. The durability and sustainable nature of the material make it a perfect option. Due to the sulphate pulping process, wood chips are digested into lignin and cellulose fibres. These fibres give tear resistance and tensile strength to kraft boxes. 

The natural colour of kraft is due to the presence of residual lignin that gives a rustic look. However, this colour can be removed when higher aesthetics and white kraft is required as wholesale packaging material. It has a GSM of 40 to 300, which makes it adaptable to different packaging requirements. Kraft has porosity and breathability that give it higher burst strength and tear index. From grocery bags to corrugated box liners, this material can be used for several applications. Its types are: 

Cardboard 

Technically, cardboard is known as paperboard. It is thick and has a GSM of 200–800, a calliper thickness of 0.3–1.0 mm. This paper has a higher stiffness and better foldability with superior uniformity that makes it suitable for. It makes it suitable for structural packaging. Custom cardboard boxes are manufactured with multi-ply construction, where the different fibre layers are combined to give strength and printability without enhancing the packaging cost. 

The external two layers of this personalised packaging material are composed of chemical pulp, while the middle layer has mechanical pulp with bulk and opacity. To enhance the whiteness and ink receptivity of cardboard can be enhanced by the application of calcium carbonate and synthetic polymers. This packaging material for small businesses is classified into several types based on bleaching level and pulp source, such as: 

Corrugation 

Corrugated cardboard is a multilayer material with at least one fluted layer inside it. Corrugated packaging material boxes have rigidity and cushioning capacity, along with compression strength due to the presence of a middle fluted layer. This material is ideal for shipping and retail packaging boxes. 

To manufacture the flutes, the semi-chemical pulp paper is passed through corrugated rods that press it into a wavy structure. Starch-based glues are used to bind the inner layer with the outer two liners to form a strong yet lightweight structure. The flute geometry consists of height and pitch, which directly affect the mechanical performance of the paper. As a packaging material wholesale provider, we give several types of corrugated material, such as:

Rigid Board 

If you are running a luxury brand in the UK, then rigid custom packaging material in the UK is an ideal option for longevity and a high-end look. It is a thick and non-folding material that is manufactured by compressing recycled fibres and pulp waste into dense sheets. Typically ranging from 800 gsm to 2500 gsm (1–4 mm thickness), rigid material is commonly used for gift and apparel boxes. It does not have inherent fold lines due to its extremely stiff and durable structure. 

Due to its course surface, this material is rarely converted into printed packaging material boxes directly. It is wrapped or laminated into printed and coated paper that allows advanced printing and add-on incorporation. The durability and dimensional stability of rigid material make it one of the top choices to manufacture custom boxes. Its subtypes are as follows: 

Pre-Printing Coating Process 

Paper-based packaging material products are not inherently easy to print. They have to be treated with substrates to ensure a smooth and quality printing with barrier properties. Different additives are used on the paper surface, such as: 

• Sizing Agents: They are applied internally to the pulp stage on the surface of the paper to control ink absorbency and liquid penetration. 
• Clay or Calcium Carbonate Coating: These coatings provide a smooth and bright surface area for uniform printing with improved ink holdout. 
• Surface Calendering: Surface calendaring is done via heated rollers to compress the fibres and enhance the glossiness and density of the paper.
• Primer Coating: Primer coating is applied for digital and UV printing to ensure proper adhesion of inks and coatings. 

Box Designings And Customisations 

To get promotional and unique packaging, we have to use several design techniques on the box’s material. Printings and post-printing coatings are the primary things that are used to get unique and promotional packaging. The packaging material boxes with logo are further made elegant and aesthetic with the use of custom add-ons. Brands can select the box styles of their choice or based on their product requirement to get the most elegant and alluring product presentation.
