ES desiccant bag variants
Clay-Based Packaging Desiccants
ES bags are clay-based packaging desiccants filled with calcined bentonite clay impregnated with calcium chloride. They are used to protect products, parcels, cartons, individual packs and bulk packaging from moisture during storage, handling and transport. The appropriate variant is selected according to the product, package size, barrier properties and expected storage or transport time.
ES Product Range
The ES range includes variants for packaging, storage and transport. Standard ES bags are used in parcels, cartons and bulk packaging, while ES K and ES Clay are intended for larger cargo spaces. Variants differ in grammage, construction and method of use. Selection depends on the product, package size and storage or transport time.

Additional Product Protection During Storage and Transport
Packaging desiccants are placed inside packages to reduce the risk of moisture exposure during storage and transport. They are a practical solution for companies packing goods in parcels, cartons, pouches, bulk packaging or other moisture-sensitive packages.

ES desiccant sachets for moisture protection in industrial packaging Part of Active Packaging
ES products are used as part of active packaging systems where moisture control is required inside the package or cargo space. Depending on the variant, they can be applied in individual packs, cartons, bulk packaging and selected transport applications.
Clay-Based Sorption Material
Standard ES bags are filled with calcined bentonite clay impregnated with calcium chloride. This combination provides high moisture sorption capacity, which is important for longer storage, transport and protection of products in larger packages.
In many packaging and transport applications, ES bags can be used as a direct alternative to classic silica gel packets. Compared with typical silica gel sachets, the ES material offers higher moisture uptake, especially where longer exposure time or larger package volume is involved.
Standard and Transport Variants
The ES range includes standard packaging variants as well as larger transport versions, such as ES K and ES Clay. Transport variants are designed to help reduce the risk of moisture accumulation and condensation in larger load spaces during sea, road and intermodal transport.
Selection Criteria
The right variant depends on the product type, package size or cargo space, barrier properties, initial moisture level and planned storage or transport time.

Desiccant sachet material with Tyvek-type laminate and bentonite clay filling Bag Construction
The sorption material is packed in bags adapted to the product variant and grammage. Standard ES bags, from 1 g to 500 g, have a two-layer construction: one side is made of Tyvek® and the other side of PE/PP laminate. Tyvek® allows water vapour to pass through and helps reduce dust release, while the PE/PP laminate strengthens the bag structure.
ES K and ES Clay transport variants are made of spunbond-type nonwoven material and are intended for higher grammages and transport applications.
Protective Foil Packs
The bags are packed in protective foil packs that limit contact with moisture before use.
Outer Cartons
Protective foil packs with ES bags are packed in outer cartons with standard dimensions:
– 315 × 300 × 240 mm
– 315 × 300 × 280 mmPallet Packaging
For larger orders, cartons can be prepared for shipment on Euro pallets or industrial pallets, depending on quantity, product type and logistics arrangements.

Where are ES desiccant bags used?
ES bags are used in individual packages, cartons, pouches, bulk packaging and transport crates. Standard variants are mainly intended for protecting packed products, while larger ES K and ES Clay versions can be used in closed cargo spaces and transport applications.
Typical applications include:
- parcels, cartons and bulk packaging,
- export and storage packaging,
- mechanical parts and metal components,
- electronics and technical components,
- technical chemicals and moisture-sensitive products,
- selected food-related products, according to documentation and application scope,
- metallurgical products and corrosion-sensitive parts,
- products requiring reduced risk of caking, moisture exposure or packaging quality loss.

PZH attestation for ES desiccant bags used in packaging applications Product Documentation
ES desiccant products are supplied with technical documentation confirming their intended use in packaging, storage and transport applications. Depending on the product variant, documentation may include information on desiccant requirements, restricted substances and the scope of use for selected product groups.
Compliance with EU Requirements
ES products are declared as DMF-free and, depending on the variant, may comply with selected requirements for restricted hazardous substances, according to manufacturer documentation.
- DMF-free – free from dimethyl fumarate.
- RoHS – compliance with restrictions on selected hazardous substances, where applicable to the product variant.
Technical Standards
Selected ES variants may meet technical requirements and standards used for desiccants in packaging and transport applications:
- DIN 55473
Approvals and Product Use
Selected ES variants may be used to protect products requiring a confirmed application scope, including selected food-related products, according to the scope of the PZH hygienic approval and product technical documentation.
The applicable scope depends on the specific bag variant, packaging material, method of use and requirements for the protected product. TDS/SDS and additional technical documents are available on request.

ES Desiccant Bags as an Alternative to Silica Gel Packets
Silica gel packets, also known as silica gel sachets, are one of the most common solutions for protecting products against moisture. However, they are not always the best choice when the packaging, carton or transport space requires higher moisture uptake. ES bags can be used as a direct alternative to standard silica gel packets. Their advantage is high sorption capacity and the possibility to select the grammage according to the product, package size and transport conditions. In many B2B applications, the presence of a small silica gel packet is not enough — the actual moisture uptake during storage or transport becomes more important.
When to Choose ES Bags Instead of Silica Gel?
ES bags are worth considering for longer storage periods, changing transport conditions, larger cartons, crates, pouches and bulk packaging. In such applications, classic silica gel sachets may offer too little capacity in relation to the amount of moisture present inside the package or cargo space. The ES filling, based on calcined bentonite clay impregnated with calcium chloride, provides high moisture sorption capacity. For many packaging, logistics and industrial applications, ES bags are a stronger and more practical alternative to typical small silica gel packets.
Silica Gel or ES Bags — What to Choose?
Silica gel can still be a suitable solution for small packages, short storage periods or applications where the customer already has specific material requirements. If the problem is higher moisture level, longer transport time, bulk packaging or the need to select a specific grammage, ES bags should be considered as a higher-capacity alternative. The selection should not be based only on the material name. The key factors are sorption capacity, package size, barrier tightness, initial moisture level, storage time and transport conditions.
