Closure and Lid Options for Kraft Drums

Kraft drums are essential for transporting and storing all kinds of products. They need closure systems and lids that ensure the safety and integrity of the contents and efficiency in logistics.

Choosing the right components is key: they influence not only product protection but also the optimisation of packaging and distribution processes.
Below are the features and applications of our company’s main closure and lid options.

Crossbow closure for Kraft drums

The leaf-spring closure, also called a strap closure, is a robust and reliable solution to ensure that the closure fits the body of the container. Its design allows the container to be sealed to ensure the inviolability of its contents.

  • Variety of closures: Each closure (metal, plastic, wood), by its design, needs to have a specific profile to ensure the correct closure of the container. This is independent of the capacity of the container, which can be between 5 and 200 L.
  • Ease of handling: It can be opened and closed as many times as needed, avoiding contamination of the contents.
  • Optimal sealing: By exerting uniform pressure on the lid, the leaf spring closure ensures an airtight seal, essential for the preservation of products sensitive to humidity or oxidation.

Kraft drum lids

The selection of the right lid is as important as the closure system. Each material offers different properties to suit the specific needs of the product and storage conditions.

Tablex lid for Kraft drums

The tablex lid, made from pressed wood fibres, is an economical and environmentally friendly alternative. Its lightweight and ease of use make it suitable for products that do not require an extreme barrier against moisture or severe impacts.

  • Eco-friendly material: Composed of wood fibres, it contributes to a more sustainable supply chain.
  • Versatility: Suitable for a wide range of powder, granular or solid products, where absolute tightness is not the main critical factor.

Plastic lid for Kraft drums

Plastic lids (high density polyethylene – HDPE) offer excellent resistance to moisture, most chemicals and impact. They are a popular choice for products requiring increased protection against external agents.

  • Chemical resistance: HDPE gives high corrosion resistance, making it suitable for non-aggressive chemicals.
  • Moisture barrier: They provide an effective seal against moisture ingress, prolonging the shelf life of hygroscopic products.
  • Durability: Their robustness ensures consistent protection during transport and storage.

Metal lid for Kraft drums

The metal lid (galvanised or lacquered sheet metal) is the superior solution when maximum protection and sealing are required. Its strength and resistance to deformation make it indispensable for hazardous, sensitive or high-value products.

  • Absolute tightness: Provides an almost impenetrable seal, crucial for liquids, volatile products or those requiring total protection against contamination.
  • Superior strength: Withstands the most demanding storage and transport conditions, including stacking and rough handling.
  • Reinforced security: Galvanised or lacquered sheet metal adds an extra layer of security, especially relevant for substances that could compromise the integrity of other materials.

The choice between these options will depend on a thorough analysis of the characteristics of the product to be packed, the applicable transport regulations and the expected storage conditions.

An informed decision will not only ensure product safety and quality but also optimise costs and operational efficiency.
