  It is also referred to as egg crate foam due to its similarity with an egg crate on the cooler lid. Convoluted foam is included in cardboard packaging boxes as top and bottom cushions due to its inexpensive price that protects delicate items during shipping. It has great versatility and is widely used across numerous industries.

• Custom Foam Inserts

  Custom foam inserts are specifically designed and manufactured based on customers' specifications, dimensions, and requirements. Usually, they are CNC machined or hand cut from various foam types comprising high-density polyurethane, ASTM Ethafoam, and viscoelastic memory foam. Custom foam inserts provide unmatched protection for fragile items and luxury products, especially during shipping and storage. Although they are more costly than other general packaging options, they offer added value through improved safety and branding.

What Makes a Cardboard Box with Foam Inserts Durable?

Durability can be achieved with the correct selection and combination of materials for the foam and cardboard box. A cardboard box with foam inserts is made stronger in the following ways:

• High-Quality Corrugated Cardboard

  The insert box is usually made of thick, double-walled corrugated cardboard for premium-quality boxes. Double-walled corrugated cardboard features two layers of kraft paper on the outside that protect the box and a wavy layer of paper in between that gives it structure, rigidity, and shock-absorbing qualities. This construction improves resistance to punctures and crushes, which, in turn, enhances box durability. In addition, the use of high-quality adhesive ensures that the layers of cardboard remain well bonded, even under stress.

• Moisture-Resistant Coatings

  Applying a moisture-resistant coating, such as a thin plastic layer or special varnish, improves the durability of cardboard boxes. These coatings help in minimising the risk of damage from water, humidity, and environmental conditions, thus making foam boxes ideal for storage and shipping for companies.

• Sketch and Manufacturing

  Foam inserts, such as Pick-and-Pluck or die-cut foam, fit tightly into the cardboard box, preventing movement in transit. This snug fit minimizes strain on both the foam and the cardboard, keeping them in great shape for longer. Moreover, thin sheets of thermoplastic foam are durable enough for frequent use in retail displays or storage solutions.

• Reinforced Corners and Edges

  In many sturdy designs, the corners and edges of the cardboard box can be reinforced with additional layers of cardboard or special corner protectors. Further, these reinforcements help improve the structure and integrity of the box, preventing collapse or damage during transport. They also offer extra cushioning for the foam inserts and the packaged product. Indeed, reinforced corners are essential for applications where the box is likely to be stacked or subjected to heavy loads.

• Stress Points

  The design of durable cardboard boxes generally comes with extra layers of cardboard or paper strips at stress points, such as the base and lid junctions or box corners. This helps to enhance the strength and durability of the box by minimizing the chances of splitting or collapsing under heavy loads or during rough handling.

How to Choose a Cardboard Box with Foam Inserts

Choosing the right cardboard box with foam inserts can be daunting when considering the following factors:

• Nature of product

  The kind of product a business deals with should influence the choice of box. A business retailing electronic gadgets, mechanical tools, or glassware should invest in a general box with a visual foam insert. A business selling items in bulk should opt for a general box with typical foam inserts.

• Weight of product

  Heavy items require thicker foams and stronger boxes. Manufacturers use double-wall cardboard for such products and make thicker foams. Pink insulation foam is known for its durability and strength, helping it provide protection during shipping.

• Foam quality

  Foam quality is gauged by its density and hardness. High-density foams are put to use in luxury packaging boxes due to their sturdiness. Businesses should go for long-lasting foams with a high density that can take up pressure without losing shape.

• Shipping method

  The shipping method affects the choice of box. In the case of shipping by air, manufacturers use lighter boxes and dispersive foams. If boxes are shipped by sea, heavier boxes with denser foams are used.

• Environmental factors

  Manufacturers consider environmental factors like extreme cold or humidity when choosing a cardboard box and foam insert. For items sensitive to temperature or moisture, they reinforce the box using plastic sheets or foams and add moisture barriers.

• Branding opportunities

  Cardboard boxes offer great branding opportunities to businesses. A box's design, color, and material define it. Retailers create their brands in a cardboard box by adding their logos and using different colors.

• Budget considerations

  Businesses when choosing a packaging solution consider their budget. Foam inserts can be costly, depending on the kind of foam used. Manufacturers put a logo on every available space on the packaging and make it more affordable. This makes the cost of packaging lower while increasing brand awareness.
