Antimicrobial packaging systems are recognized as effective approaches to prolong food shelf life. In this context, Bio-based PA11 loaded with a food-grade zeolite were prepared using ball milling technology in the dry state. Zeolite was filled with sodium salicylate, as an antimicrobial agent, and incorporated into the polymer matrix (~50 wt % of salicylate) at different loadings (up to 10 wt %).

During the energetic ball-milling process, La 3+ ions could permeate into the pores of the zeolite and distribute evenly with Fe 3 O 4 in the zeolite structure . Scanning electron microscopy (SEM) results show that the as prepared zeolite particles are all cube in shape, which is a typical characteristic of zeolite, as shown in Fig. 2 (a).

These new active sites may help to promote the side-chain methylation reaction. However, excessive ball milling will lead to the vanishing of zeolite micropores, thus deactivating side-chain methylation activity, which indicates that microporosity plays a key role in side-chain methylation and individual basic centers cannot catalyze this reaction.
