Leak-Proof Containers

Leak-proof containers are single-use food containers with a locking lid that carry liquid and semi-liquid food without spilling. Dipack manufactures these containers at its factory in Dursunbey, Balıkesir, and sells them wholesale direct from the manufacturer to restaurants, patisseries, delis and food producers.

This page covers the differences between the series, the size table and the wholesale ordering process, so you can settle on the right container for your business before you order.

Dipack leak-proof container series: Eco, Lux and PP

Dipack produces three separate leak-proof container series, because every business has a different budget and presentation requirement. The Eco series is the economical option for everyday takeaway, while the Lux series is the upper-segment option for display case and shelf presentation.

The PP series, with its polypropylene body, suits hot service and the microwave. When choosing a series, look first at the serving temperature, then at your presentation requirements.

Leak-proof container sizes and carton quantities

Portion size and shelf height determine the right size. The table below shows the shared base sizes, lid heights and carton quantities of the Eco and Lux series, so you can plan storage and transport before you order.

Each product page also shows carton dimensions, carton volume (m³) and cartons per 40' HC container, so you can calculate export loading plans directly from the product page data.

Flat lid or high lid?

A flat lid leaves no gap between the top of the product and the lid, so it saves shelf space for salads, mezes and sliced products.

A high lid (dome lid) leaves 15-30 mm of extra space above the product, so heaped rice pudding and decorated portions travel without sticking to the lid.

• Flat lid: for example, mezes, olives, salads, sliced cheese and ready-meal portions.
• High lid: on the other hand, rice pudding, profiteroles, fruit salad and dishes with sauce.
• Square and rectangular lids: businesses that want to fit more containers on narrow shelves and in refrigerators.

PET or PP leak-proof containers: which material for which food?

PET leak-proof containers offer glass-like clarity, so they are the first choice for display cases, refrigerator shelves and cold service.

PP containers withstand heat up to 120 °C and can be heated in the microwave. As a result, restaurants with hot service choose the PP series, and patisseries with cold presentation choose the PET series. A detailed guide to the material decision: PP or PET?

How to choose a leak-proof container: 5 checkpoints

Choosing the wrong container means returns, leaks and lost shelf space. Check the five points below before you order, because each one prevents a separate cost item.

1. Serving temperature: choose PP for hot food and PET for cold presentation.
2. Portion volume: plan for an 80 percent fill rather than a heaped one; for products with sauce, choose a high lid.
3. Shelf and refrigerator layout: square shapes fit more containers, while oval shapes look better in a display case, so measure your shelf first.
4. Label area: a flat lid suits lid-top labels, and a model with taller sides suits body labels.
5. Carton and storage: also check pieces per carton and carton dimensions against your warehouse shelving.

Where are leak-proof containers used?

Businesses use leak-proof containers most for takeaway and ready-to-eat food packaging, because the locking lid prevents spills in transit. Food producers also use the same containers on filling lines, and supermarkets at their deli counters.

• Restaurants and catering: for example, takeaway portions, wet dishes, soups and sauces.
• Patisseries and dessert shops: rice pudding, baklava slices, profiteroles and clotted cream.
• Delis and supermarkets: olives, cheese, pickles, mezes and salads.
• Food producers: also hummus, dips, ready-made mezes and yogurt filling.

For containers designed for specific product groups, see the salad containers, deli containers, baklava containers and PP hot food containers pages.

How does wholesale ordering of leak-proof containers work?

Dipack, a brand of Onursan Ambalaj, manufactures its containers on its own thermoforming lines. That means you get a factory-direct quote with no middleman margin. The process has three steps: you share your requirements list, you receive samples and a quote, and then our team plans shipment by the carton.

1. Requirements list: first, send the volume, lid type and monthly quantity.
2. Samples and quote: our team then sends samples and a per-carton quote for the models you choose.
3. Shipping: finally, we agree on the carton and pallet layout together, so delivery within Istanbul and to other cities is clearly planned.

If you need a size outside the standard molds, review the reference projects on the custom packaging page. Dipack runs the whole process, from mold design to series production, under one roof.
