Why HDPE leads for milk, yogurt drinks and dairy packaging: chemical resistance, squeezability and low-temperature performance, plus neck and cap choices for dairy lines.

How to spec PET bottles for cooking oil, olive oil, soy sauce and condiments: capacity, neck finish, hot-fill limits and label choice — with food-grade compliance built in.

Food-grade PET and HDPE bottles for edible oil, sauce, dairy, juice and beverage. Material choice, capacity guidance and the certifications (FDA, EU 10/2011, Food Grade) buyers must verify before ordering.

Some products legally need child-resistant or tamper-evident closures. Know when they apply and which neck they need.

Quoted capacity is the brim, not the fill line. Plan headroom so the closure fits and nothing overflows in transit.

Decoration is where a stock bottle becomes your brand. Compare the three common methods and when each pays off.

500 ml HDPE conditioner bottle: typical specs, gram weight and dimensional tolerance, neck finish and closure fit, decoration options and inspection.

How a 100 ml PET oil bottle is specified and made: resin and wall tolerance, neck finish, closure matching, decoration options and what buyers usually order.

Why PETG suits a 50 ml cream bottle, which neck finishes and closures fit, what MOQ and lead time to expect, and where PETG is the wrong choice.

Specifying a 200 ml PET mist bottle: resin and wall tolerance, neck finish, matching a fine-mist sprayer or cap, decoration limits and MOQ.
