What You'll Learn
Boxed wine's environmental impact
The boxed wine packaging was invented in the 1960s by Australian winemaker Thomas Angove. It involves placing a plastic bag inside a corrugated cardboard box. The bag is then filled with wine and sealed with a nozzle. This packaging has gained popularity as a more sustainable alternative to traditional glass bottles.
Boxed wines have a lower carbon footprint than bottled wines. The production and shipping of heavy glass bottles have a significant environmental impact. In contrast, boxed wines are more energy-efficient to produce and transport. They are lightweight, stackable, and do not shatter easily, reducing the carbon emissions associated with transportation. According to the New York Times, switching to boxed wines for wines consumed within a year could reduce greenhouse gas emissions by approximately two million tons, equivalent to removing 400,000 cars from the road.
The use of bag-in-box technology in boxed wines also contributes to sustainability. This technology prevents oxidation, allowing the wine to stay fresh for longer after opening. As a result, it minimises wine waste and reduces the need for frequent purchases. Additionally, some boxed wine brands use recycled materials, soy-based inks, and biodegradable packaging, further reducing their environmental impact.
However, one concern with boxed wines is the presence of Bisphenol-A (BPA) in the plastic bags. BPA is a synthetic chemical used to strengthen plastic food containers. It has been linked to potential health risks, including altered brain development, behavioural changes, and increased risk of certain cancers. While some boxed wine manufacturers use BPA-free packaging, it is not universal, and consumers must read labels carefully to make informed choices.
Overall, boxed wines have the potential to significantly reduce the environmental impact of the wine industry. By choosing boxed wines with eco-friendly packaging and BPA-free liners, consumers can lower their carbon footprint, minimise waste, and support sustainable practices in the industry.

Plastic bags in boxed wine and BPA
The concept of storing wine in plastic bags within a cardboard box was pioneered by Australian winemaker Thomas Angove in the 1960s. This packaging format, known as Bag-in-Box (BIB), offers several advantages over traditional glass bottles, including reduced manufacturing costs, lighter weight, improved stackability, and shatter resistance. Each BIB package can hold about four bottles' worth of wine and prevents oxidation, keeping the wine fresh for up to six weeks after opening.
While boxed wine is often promoted as a more sustainable and eco-friendly alternative to glass bottles, concerns have been raised about the plastic components used in this packaging format. One of the primary concerns centres on the presence of Bisphenol-A (BPA), a synthetic chemical used to strengthen plastic food containers and other items. BPA has been linked to various health issues, including altered brain development, behavioural changes, a predisposition to certain cancers, reproductive harm, diabetes, obesity, and cardiovascular disease.
It is important to note that the presence of BPA in boxed wine is not universal. Some wineries and packaging manufacturers have made concerted efforts to eliminate BPA from their products. For instance, Scholle Packaging, one of the largest wine box manufacturers and the inventor of the BIB system, uses only BPA-free #7 plastic in their bags. Notable boxed wine brands such as Perini, Campo Largo, and Bota Box also utilise BPA-free packaging.
To make informed purchasing decisions, consumers can refer to the labels on boxed wine products. Reputable wineries that offer boxed wines containing BPA typically disclose this information on their packaging. By reading the labels, consumers can identify whether the product contains BPA or if it is explicitly advertised as BPA-free.
While the presence of BPA in plastic bags used for boxed wine is a valid concern, it is worth noting that the impact of BPA exposure through wine consumption specifically has not been extensively studied. Additionally, the wine industry is evolving, and there is a growing trend towards more sustainable and eco-conscious packaging options. As consumers become increasingly aware of the environmental impact of their choices, the demand for responsible and sustainable packaging solutions, such as boxed wine, is expected to drive innovation and improvements in the industry.

How boxed wine stays fresh longer
The concept of storing wine in a plastic bag within a box was pioneered by Australian winemaker Thomas Angove in the 1960s. The wine is typically stored in a vacuum-sealed bag, which is placed inside a corrugated cardboard box. This packaging is known as Bag-in-Box (BiB) and offers several advantages over traditional glass bottles. Firstly, it prevents oxidation, keeping the wine fresh for a more extended period. Secondly, BiB packaging is more cost-effective, lightweight, and environmentally friendly than glass bottles.
One concern regarding boxed wine is the potential presence of Bisphenol-A (BPA), a synthetic chemical used to strengthen plastic food containers. BPA has been linked to various health issues, including altered brain development, behavioural changes, and an increased risk of certain cancers. However, it's important to note that not all boxed wines contain BPA. Some manufacturers, such as Scholle Packaging, use BPA-free plastic in their bags, and it is recommended to check the labels when purchasing boxed wine to ensure it is BPA-free.
To ensure the freshness of boxed wine, it is advisable to store it at a consistent cool temperature before opening. Once opened, it is best to keep the wine in the fridge, as boxed wine is more susceptible to oxidation than bottled wine. The wine should be consumed within a few weeks to a month, depending on various factors, including the type of box and storage conditions.
Additionally, the size of the box can be an indicator of quality, with 3-liter boxes generally considered better than 5-liter boxes. Checking the expiration date is also essential, as boxed wine has a limited shelf life, even before it is opened. Transferring the wine to a smaller container as it nears the end can help reduce oxygen exposure and prolong its freshness.
Overall, boxed wine can offer a more environmentally friendly and cost-effective alternative to traditional glass bottles, and with proper storage and consumption, it can stay fresh for a reasonable period.

Bag-in-box (BiB) packaging and its rarity in independent technical assessments
The bag-in-box (BIB) packaging system, invented by Scholle Packaging in 1955, revolutionized the wine industry by introducing a safe and convenient way to store and dispense liquids. Despite its popularity, particularly for boxed wines, BIB packaging has rarely been subjected to independent technical assessments. This lack of comprehensive evaluation warrants further examination.
The BIB system comprises a double-welded plastic bag placed within a corrugated cardboard box, offering ease of storage, dispensing, and resealing. Its design extends product shelf life, maximizes product evacuation, and reduces the amount of residual product, making it environmentally friendly. However, the plastic component of BIB packaging has sparked concerns among consumers.
The plastic bags in BIB wine boxes have been a subject of debate due to the potential presence of Bisphenol-A (BPA), a synthetic chemical used to strengthen plastic food containers. BPA has been linked to various health issues, including altered brain development, behavioral changes, and increased risk of certain cancers. While some manufacturers, like Scholle Packaging, use BPA-free #7 plastic, other brands may vary in their plastic composition, leaving consumers unsure about the safety of their wine choices.
The rarity of independent technical assessments on BIB packaging may be attributed to a few factors. Firstly, BIB technology is relatively new in wine packaging, and the focus has primarily been on its functional and environmental advantages. Secondly, the wine industry has traditionally viewed boxed wine as "cheap," which may have influenced the prioritization of assessments. Lastly, the variety of plastic types and compositions used in BIB packaging across different brands could complicate standardized testing and assessments.
To address this gap in independent technical assessments, organizations like Peak Packaging in the UK and Poland have emerged as dedicated liner solutions providers for BIB systems. They offer in-house testing to ensure the hygiene and integrity of the liner and fitment, preventing leaks and contamination. Additionally, companies like CDF Corporation emphasize creating high-quality packaging systems tailored to their customers' needs, utilizing advanced technologies such as Deep Draw Vacuum-Forming, Blow Molding, and Heat Sealing. These efforts contribute to enhancing the overall safety and reliability of BIB packaging.
