Paper Window Tubs: Which Size Should You Choose

 Package size is an important factor in controlling portions, packaging aesthetics, cost, and the overall customer experience. For food service industries such as quick service restaurants, cafes, cloud kitchen services, caterers, and even food brands, the paper window tub should be selected based on the food item it contains. Our 600ml, 750ml, and 900ml window tub options provide a range of features to suit a variety of packaging needs and serving sizes.


We are committed to making good-quality, eco-friendly paper tableware at Ishwara. Here is a simple comparison of 3 paper window tub sizes to help you choose the right one for your food business.

Why is Paper Window Tub Size Important?

Packaging size is more than just measurements. It affects portion size, product appearance, and handling.

A tub that's too small will make a portion look squeezed. It can hurt presentation and handling. On the other hand, a tub that is too large will be expensive and will make smaller portions look insufficient.

The right size will combine portion size, presentation, cost, and convenience. It will also help standardize portions across multiple locations of the same brand.

Ishwara’s paper window tubs are a reliable packaging option to be used along with traditional plastic packaging. The clear window lets customers see what’s inside the food before they open it.

Here’s a handy comparison table to help you see what paper window tub sizes work best for different portion sizes and food business needs.



Size

Suitable For

Suitable Business Application

600 ml

Small to medium portions

Sweets, snacks, side dishes, light meals

750 ml

Medium portions

Rice meals, pasta, noodles, dessert

900 ml

Big portions

Combination meals, big takeaway portions


600ml Paper Window Tub: When to Choose It?

The 600ml paper window tub is apt for controlled portions. This size has plenty of space for lots of snacks, desserts, sides, and takeaway food without the extra volume of packaging.


It is especially good for:


  • Bits of ice cream and dessert

  • Fries and other loaded munchies

  • Pasta in small amounts

  • Light meals and salads

  • Dry snacks & starters

  • Takeaway snack combinations


If you standardize smaller portions, a 600ml paper window tub is a good option for your business. And this size allows you to keep the presentation compact when you don’t need extra headspace.

750ml Paper Window Tub: The Balanced Option

A 750ml paper window tub lies between compact and large-capacity packaging options. It is ideal for a wide selection of takeaway products, while still being a sensible package size. It is suitable for food like: 

  • Noodles & Pasta

  • Rice dishes

  • Curries and sides

  • Confectionery

  • Salads

  • Snack mix and match

  • Portions for average-sized take-aways

 This is a great package for food business owners who offer a wide variety of menu items. With just one packaging size, you will meet all the order needs of your customers.

900ml Paper Window Tub: Ideal for Larger Portions

The 900ml paper window tub is designed for food businesses with larger portions or meals that need extra space.

This size can be helpful for: 

  • Big bowls of noodles

  • Combo meals

  • Big servings of desserts

  • Food with multiple parts

Large portions often require more headroom to avoid compression. This matters if you’re packaging food with toppings, sauces, or garnishes that need to stay visually appealing. Also, a 900ml tub is a good fit for businesses where customers expect a portion large enough to fill up.

We suggest matching 900ml packaging with products that really need the extra capacity. This way you will keep your portion discipline and avoid unnecessary packaging costs.

How to Choose the Right Paper Window Tub Size?

The best approach is to evaluate the food portion before choosing the packaging. Here are the top 3 important factors to consider.


  • Start With Your Standard Portion

First, determine your food's actual serving size. Measure the portion rather than estimate it.

If the portion easily fits within 600ml, you may not need 750ml or 900ml. Medium portions can fit comfortably in 750 ml, while larger portions may need 900 ml.


  • Take Into Account the Food's Form and Density

Not all foods occupy the same space. Loose foods like fries and salads require more volume than dense foods. This can also include pasta, noodles, rice, and mixed meals, which may need a little extra space for the sides.

So the choice of packaging will have to consider the volume and the shape of the food.


  • Don't Fill the Tub to the Top

Leaving some headspace helps prevent contact between the lid or window and sauces or toppings.

This is especially important for deliveries, since the package will be moving to the recipient.


Final Checklist Before Ordering Paper Window Tubs

Before choosing a preferred size of packaging, please note the following:

  • Check the real volume of the portion

  • Consider food density and its shape

  • Leave enough headspace

  • Think of toppings and sauces

  • Consider the delivery conditions

  • Compare packaging price and portion size

  • Keep the packaging consistent for similar menu items

Conclusion

The right paper window tub should suit your portion, food, presentation, and delivery requirements. A 600 ml tub suits compact portions; 750 ml is more versatile and suitable for medium-size portions. For large quantity meals, 900 ml is the best option because it offers more capacity and better food presentation.
