Food Packaging Tricks

Are you paying for empty space?

Last updated: 04 October 2016

Have you ever torn open a packet of chips only to discover the bag is half-empty? Or opened a box of snack bars to find they’re much smaller than you expected? And that expensive jar of moisturiser – why is it only half the size of the box it comes in?

You’ll find plenty of products brimming with lots of empty space. Manufacturers might blame packaging processes or labelling information, but you’re probably just wondering what on earth happened to the rest of your product.

The case of the disappearing products

A classic packaging trick is to shrink products and keep the packaging the same. In some cases, products are redesigned to mask the smaller size. Foods such as cereal in boxes might go down in weight, but the box stays the same or is altered in height and width so it’s not immediately noticeable.

Canny CHOICE readers have spotted examples of shrinking products over the years:

The size of chocolate bars is reduced, but the number of pieces stays the same.

Toilet rolls still look the same on the outside, but have fewer sheets because manufacturers have increased the diameter of the cardboard tube in the middle.

Breakfast cereals shrink in packet size but not in box size.
Man-size large tissues shrink in size, but not in name despite being significantly smaller.

Packets of chips shrink in contents, along with price, but the packet stays the same size so it looks like a saving.

Some soap looks the same until you take off the wrapper and discover the new bars have been cunningly reshaped to be more concave so you actually get less soap per bar.

Which bag of sugar is bigger?

These two packets each contain 1kg of raw sugar, but one uses more packaging than the other and takes up markedly more shelf space − and is, therefore, more likely to attract your attention in the supermarket than the smaller packet. One theory is that it’s designed to make you think you’re getting more than from the competitor’s brand.

The manufacturer of the larger bag offers other reasons for its choice of packaging. Sugar Australia, which makes CSR products, says while the bags used for its white and raw sugar are of a similar size, the packaging material and design are different. The white sugar bags are made of paper and the head space is folded and glued down, whereas the bag for raw sugar is plastic and not folded over. The company says this is because raw sugar is hygroscopic, meaning it takes up and retains moisture readily, so plastic bags provide better protection.

Big on labels, small on size

The manufacturers argue that the information that needs to be included on the label won’t fit onto a smaller bottle in the correct font and style.

In other cases, food manufacturers say that the limitations of packaging machines means that certain products are packed with more air because the packaging can’t be reduced. This equipment is a sizable investment so manufactures are probably reluctant to replace equipment unless they have to in order to make savings or comply with the law.

Don’t fall for the shrink tricks

Check the weight of the package or the number of items it contains. A larger package doesn’t always mean more contents.

Compare prices for a comparable unit by volume or weight. Unit pricing allows you to compare prices easily between grocery products packaged in different sizes. It’s now mandatory for larger store-based, online and grocery retailers.

Don’t buy a product if you believe it’s deceptively packaged. Let the company know why you’re rejecting it and, if you’re concerned you’ve been misled, report the matter to the ACCC or your state or territory’s Office of Fair Trading.
