A good range of plastic bags and other containers is essential both for the collection of habitat samples or inidividual specimens in the field and for the storage of voucher specimens.
Widely available in a very large range of sizes and thicknesses; a limited range available (usually rather expensively) from supermarkets and kitchen supplies shops. Self-sealing ("zip-lock") bags are useful; some bags have white panels which are easier to write on. Remember that polythene degrades rapidly on exposure to UV light: if you expose polythene bags to direct sunlight, they are likely to start to become brittle within a few months. It is important to exclude light if you use polythene bags for longer-term storage.

Containers (see also below, containers for small shells)
A range of materials (glass, different plastic, card) are available, in a huge range of sizes. Glass is probably best avoided in the field in case it breaks, but very stable in laboratory use. Plastics are very varied: some are transparent (but often scratch easily); others are opaque; some are brittle while others are tough. Think particularly about the suitability of plastic containers for longer-term storage, either because the plastic may break down, or because chemicals from a plastic may affect shells. PET is probably better for longer-term storage than polythene and plastics that contain plasticisers. Think also about whether you need containers to be waterproof. Be cautious about wood boxes and cabinets: many kinds of wood (oak, for instance, or MDF) produce acids which may damage shells.

A cheaper alternative is to use gelatine capsules, though care needs to be taken to make sure that they do not get damp:
