bottle packaging

Have you ever wondered why drinks are packaged in glass, metal, or plastic? There are a few properties to consider when choosing the right packaging material for a beverage. Attributes such as package weight, recyclability, fallibility, clarity, durability, breakability, dimensional stability, and heat resistance play a significant role in the selection process. This section explores the properties and feasibility of the three main beverage materials: plastic, glass, and metal. There are multiple bottle packaging boxes that you can use for it. Many of them are as follows. 

Suitable Packaging 

Which packaging is best for you ultimately depends on the product type in the first step. Ferringer says, “It’s often forgotten that packaging needs to fulfill important functions such as protection, storage, and transport, and informational functions such as ingredients, sugar content, best before dates, barcodes, and single-use labels.”

The maximum loading weight of each truck can be as high as 38 tons. The rule is, the lighter the package, the more liters the truck can carry. For example, a glass bottle alone weighs 500 grams, but a single-use plastic bottle weighs only 25 grams! That’s why we separate glass bottles from single-use plastic bottles.

In particular, in the case of glass bottles, the bottles are transported. In contrast, in the case of cartons, bottles, and PET bottles, the beverages are first transported to the intended location. It makes shipping more efficient. The shape of the packaging also plays an important role. Conical glass bottles require more space than cans and beverage packs.

Adequate Packaging 

For PET bottles, there are single-use and recyclable products. Recycled PET bottles have thicker walls than single-pass PET bottles. Environmentalists demonize all types of plastic, but PET bottles have a better ecological balance than their reputation.

Therefore, a decisive factor in the correct choice of packaging in terms of sustainability is the length of the transport route. If the transport route from the gas station to the supermarket is not very long, returnable bottles are the most suitable way.

In the life cycle assessment of reusable bottles, it is not only the transport route that matters but also the number of times the bottle is reused,” says Roland Fellinger. For a good life cycle assessment, you can recycle a returnable glass bottle 15-20 times. On the other hand, you can recycle plastic bottles at least 8-10 times. Less recycled bottles end their life cycle; even recyclable bottles have a low LCA.

Types of Bottle Packaging Products for Beverages

Plastic 

Did you know that the shelf life of plastic bottles is to ensure that the product meets the brand’s taste and consistency requirements? PET bottles have a good shelf life but are shorter than glass or metal containers of the same size. However, improvements in processing technology and barrier properties, coupled with faster lead times, mean that package shelf life is adequate for many applications.

Plastic bottles for beverages can be easily shaped. For pressurized products such as soft drinks, maintaining the shape of the package under high internal pressure is a challenge. However, technological innovations, processing techniques, and improved materials allow plastics to be shaped into almost any shape under pressure.

Plastic bottles are clear, lightweight, refillable, and safe when dropped. In the case of plastics, recycling may be limited, but improvements in technology have enabled a higher percentage of plastics to be recycled.

Glass 

Glass is a classic material. Even in early Egypt, Glass was used as a container. As a packaging material, glass is heavier than metal or plastic. Still, its long service life, high print quality, and low cost make it a competitive base material. Glass bottles have a high recycling rate, with up to 60-80% of new glass bottles being post-consumer materials. Because glass can withstand high-temperature cleaning and can be reused many times, it is often used as the first choice for refills.

Glass packaging is preferred for its transparency and barrier properties. It allows packaging with a longer shelf life without worrying about loss of carbon dioxide or entry of oxygen.

New processes and coatings improve the fragility of glass bottles. Significant weight reduction and reinforcement technologies make Glass a more durable, consumer-friendly package. When it comes to packaging of 60ml bottle boxes, shape stability is an important factor in brand identity and consumer innovation. Glass is highly adaptable and can hold its shape. Beverage brands use the “coolness” of glass containers to persuade consumers to opt for chilled bottles.

Metal

Metal cans have unique properties when considered for beverage use. Metals are important in terms of weight, recyclability, and safety. Their unique dimensional stability and transparency are not their strong suits. Casting cans are made possible by new processing techniques, but they are expensive and limited to small market applications. The metal retains light, holds carbon dioxide, is immune to oxygen, and has good beverage preservation properties.
