Metal-free, all-plastic and mono-material describe different aspects of a package. Metal-free describes the absence of metal within a stated scope. All-plastic describes the materials used. Mono-material describes a design based on one material type. None of these terms, by itself, tells you whether a complete package can be collected, sorted and recycled where it is sold. Understanding the difference helps you choose components and describe them accurately.
Metal-free: first establish what is included
When reviewing a pump, ask whether “metal-free” applies to the entire dispenser or only to the product-contact path. A pump can keep its metal spring outside the product path while still containing metal elsewhere. That is different from a pump with no metal parts in its complete construction.
APG offers all-plastic dispensing options that replace metal components with plastic parts. For a specific project, confirm the complete assembly: pump, closure, any decorative collar and other components. A metal-free dispensing mechanism paired with a metal outer collar should not be described as an entirely metal-free package.
Metal-free is not, on its own, a complete materials specification. Other non-metal materials can exist in packaging. Ask for the material breakdown instead of assuming the term means every part is plastic.
All-plastic: more than one plastic may be present
An all-plastic component uses plastic throughout, but it may combine different polymers. For example, polypropylene (PP) and polyethylene (PE) can appear in different parts of an all-plastic pump. Those are both plastics, but they are not the same resin.
APG’s catalog includes all-plastic components alongside models specifically described as mono-material. This gives a brand different structures to consider. Choose the dispenser that meets the application, then review its materials and the intended recycling route. Do not assume that a product’s appearance reveals its construction.
Mono-material: one material type within a defined scope
In plastic packaging, mono-material usually describes a component or structure based on one polymer family, such as PP. The broader term can also apply to other materials. Always ask which parts the description covers and whether labels, inks, coatings, seals or attachments introduce additional materials.
APG lists its Infinity V2 lotion pump as a PP mono-material design. That describes the listed component. Pairing it with a bottle of a different material does not make the assembled pack mono-material. Review the bottle and dispenser together before using a claim about the complete package.
A quick comparison
| Term | Question it answers | What to check next |
|---|---|---|
| Metal-free | Is metal absent from the stated component or product path? | Whether the claim covers the whole dispenser and its decoration. |
| All-plastic | Is the stated component made from plastic parts? | Which plastics are present and how they interact in recycling. |
| Mono-material | Is the stated structure based on one material type? | Its scope, attachments, coatings and the complete package. |
| Recyclability | Can this package enter an appropriate recycling system? | Design compatibility, collection, sorting and the destination market. |
Recognition applies to a specific design and scope
APR’s 2021 Meets Preferred Guidance recognition covered APackaging Group’s Infinity Pump Series all-polyolefin lotion pumps for HDPE and PET bottles. RecyClass also announced approval of Infinity Pump technology for the European HDPE recycling stream, with conditions including a pump weight no greater than 26% of total packaging weight. Other approval conditions still apply.
These are meaningful design assessments, but they do not cover every APG component or automatically establish a claim for every finished pack. Ask for the relevant recognition letter and have the chosen configuration checked against its conditions. A qualification such as “where facilities accept it” is not a substitute for evidence supporting a recyclability claim.
Bring a clear materials brief to APG
Specify your dispensing format, formula, desired output, bottle and target markets. Then explain the objective: no metal in the product path, no metal anywhere in the dispenser, a particular resin, or compatibility with a defined recycling stream. These are different requirements and should be reviewed separately.
Material selection also needs formula and dispensing tests. It does not establish shelf life or universal compatibility. Discuss your packaging project with APG to compare suitable structures and confirm the documentation for your selected model.
