Retailers moving away from plastic void fill encounter several paper-based alternatives, and two of them are commonly confused: honeycomb paper and paper bubble cushioning. Both are made of paper, both are recyclable, and both are used for protection. But they are produced by different processes, they perform differently, and they suit different applications.
Honeycomb paper is produced by cutting a pattern of slits into a flat paper sheet and then expanding the sheet. The expansion creates a three-dimensional structure with open cells that provides compression strength and surface protection. It is commonly used for wrapping fragile items, protecting flat surfaces, and creating a structured layer inside a carton. The material is strong in compression and holds its shape well when wrapped around an object.
Paper bubble cushioning is produced by pressing the paper between embossing rollers, which creates a raised bubble pattern without cutting. The embossed structure creates air space within the paper itself, which absorbs impact and reduces vibration. It is commonly used for wrapping irregular items, filling voids, lining boxes, and separating products. The material conforms to the shape of the item rather than sitting flat against it, which holds items in place inside the carton.
The equipment difference is the practical consideration. Honeycomb paper is produced by a machine that cuts and expands the paper. Paper bubble cushioning is produced by a paper bubble machine that embosses the paper through forming rollers. A retailer that wants to produce both materials in-house needs two different machines, or it needs to choose one material and buy the other pre-made.
The application difference determines which material to prioritise. A retailer shipping framed prints, flat glass, and flat boxed items benefits from honeycomb paper's compression strength and surface protection. A retailer shipping irregular ceramics, bottles, and mixed product sizes benefits from paper bubble cushioning's conformability and void fill capability. Many retailers ship both types of product and use both materials for different parts of the packing process.
Aircosan manufactures paper bubble machines at its own facility in Foshan, Guangdong, and builds units up to 80cm wide. The machines produce cushioning from specialty kraft paper using mechanical embossing rollers, with no inflation, heating, sealing, or adhesive involved. The forming pressure adjusts automatically based on the actual paper thickness, so switching paper rolls or suppliers does not require retuning. The output length and quantity are customizable through the touchscreen.
The cost comparison depends on the product mix. Honeycomb paper and paper bubble cushioning cost different amounts per square meter, and the coverage required per order differs between the two materials. The cost comparison is only meaningful when it is calculated per order rather than per square meter, because the material that costs less per square meter may require more coverage per order.
The regulatory position is similar for both materials. Both are paper-based, both are recyclable through standard paper streams, and both fall into the same compliance category under packaging regulations. The choice between them is about performance and workflow rather than about compliance.
For retailers, the practical approach is to identify which products need compression strength and which need conformability, and to select the material that matches the majority of the product mix. A retailer shipping mostly flat, fragile items may choose honeycomb paper. A retailer shipping mostly irregular, fragile items may choose paper bubble cushioning. A retailer shipping both may use both materials and accept the equipment cost of two machines, or it may choose the material that covers the larger share of orders and buy the other pre-made.
