Bottles and jars are chosen by material, closure and compatibility with what goes inside, and a mismatch can cause leaks, spoilage or contamination. Test the container with your actual product and check any food, cosmetic or pharmaceutical rules for your market.

Glass, PET, HDPE, polypropylene and aluminium all appear in this category. Glass is inert, suits food, sauces, spirits and premium cosmetics, and does not scratch easily, but it is heavy and breakable. PET is clear and light, suited to water, juices and many personal-care items. HDPE is opaque, tough and common for household and chemical products. Polypropylene tolerates heat, which suits hot-fill and some microwaveable use. Coloured glass such as amber protects contents from light, which matters for oils, tinctures and some supplements.
The closure is where most problems arise. Neck finish specifications, usually given as a diameter and thread style, must match the cap exactly. Options include screw caps, child-resistant closures, tamper-evident seals, pumps, sprayers, droppers and flip tops. Liner material has to suit the contents: some liners react with oils or solvents. If your product is hot-filled, check that the bottle and cap tolerate the temperature. Order closures from the same supplier as the bottle where possible to reduce fit problems.
Test how the container performs with the real product: leakage, chemical reaction, colour change, vacuum or pressure behaviour and shelf-life storage. Some plastics absorb fragrances or essential oils, and aggressive ingredients can soften certain resins. Run a transit test with filled samples, including a drop test.
Containers for food and drink must be made from materials permitted for food contact, and the rules vary by market, so ask for a declaration of compliance and check what your market requires. Cosmetic and pharmaceutical containers may need documentation of cleanliness or batch traceability. Containers for chemicals or household products may need child-resistant features or hazard labelling depending on the product and market. Ask the supplier about food-contact documentation before you buy.
Bottles are bulky and low in value, so freight and storage cost a large share. They are sold in cartons or pallets with a fixed count per case, and stock items have lower minimums than custom moulds. Custom shapes, colours and decoration such as screen printing or sleeving require high minimums and tooling. Glass requires careful packing and may arrive with breakages, so ask about breakage allowance.
Questions to ask
Glass is a common choice because it is inert and withstands hot filling, and food-grade plastics are also used. Ask for food-contact documentation and check the rules for your market.
The bottle neck and cap must match in thread and diameter or the seal will leak. Buy matched components and test a filled sample.
Some plastics absorb or are attacked by essential oils and strong fragrances. Glass or a compatible resin is safer, and you should test for compatibility.
Some products such as certain chemicals and medicines require them, depending on the market. Check the rules for your product before choosing a closure.
