Bisphenol A, commonly known as BPA, is a chemical compound that has been shown to encourage the growth of a specific category of prostate cancer cells. It is often used in the manufacture of plastic products such as food containers and water pipes. Ziploc, a SC Johnson brand, offers a range of plastic storage bags and containers that are marketed as being BPA-free. However, some critics argue that the term BPA-free is a marketing gimmick, as the alternative chemicals used may be just as harmful due to a lack of safety testing. Nevertheless, Ziploc's BPA-free products provide consumers with an option to store food without the potential risks associated with BPA.

What You'll Learn
Ziploc containers are BPA-free
SC Johnson's Ziploc brand bags and containers are BPA-free, as stated on their website. Their products undergo extensive evaluation for toxicity and safety and comply with applicable quality and safety regulations. This is important because it ensures that consumers can have peace of mind when using Ziploc containers for food storage.
The availability of BPA-free Ziploc containers is advantageous for health-conscious individuals and those seeking to reduce their exposure to potentially harmful chemicals. By choosing these containers, consumers can avoid the potential risks associated with BPA, such as its impact on hormone regulation and its possible link to certain types of cancer.
Additionally, Ziploc containers offer versatility and convenience for various food storage needs. They are designed with secure locking mechanisms, such as snap-on lids or silicone seals, ensuring an airtight closure. This feature helps lock in freshness, prevent moisture from seeping in, and extend the shelf life of stored food items. Whether storing dry goods like cereals and pasta or perishable items like fruits, vegetables, and leftovers, Ziploc containers provide an optimal solution.
While the absence of BPA in Ziploc containers is a positive aspect, it is worth noting that some people have concerns about the general use of plastic for food storage. These concerns are related to the potential leeching of other chemical constituents, even in the absence of BPA. As a result, some individuals opt for alternative materials, such as glass or stainless steel, for their food storage containers. Nonetheless, for those who choose to use plastic, Ziploc containers being BPA-free is a step in the right direction.

Safety regulations and testing
Ziploc brand bags and containers are BPA-free and comply with applicable quality and safety regulations. However, it is important to understand the safety regulations and testing procedures for BPA-free plastics to ensure their safe use.
BPA, or bisphenol-A, is commonly found in polycarbonate plastics, which are hard, clear or clear-tinted, and unbreakable. While BPA exposure is considered safe at low levels by the U.S. Food and Drug Administration (FDA), there are concerns about its potential effects on health, especially in fetuses, infants, and children.
When it comes to safety regulations, it is important to look for recycling codes on plastic products. The resin identification system categorizes plastics into seven types, each with unique properties and safety considerations. For example, PET or PETE plastics, commonly used in beverage bottles and food containers, are BPA-free and have excellent chemical stability. On the other hand, polycarbonate plastics, often marked with the number 7, are likely to contain BPA.
To ensure the safe use of BPA-free plastics, it is crucial to understand their temperature thresholds and food contact limitations. Even FDA-approved materials need specific usage guidelines to maintain their safety profile. For instance, PET bottles show increased chemical release above 28°C, and PP (plastic code 5) and Tritan are recommended for high-heat applications. Additionally, it is important to store BPA-free containers away from direct sunlight and heat sources to prevent harmful chemical leaching.
Extensive third-party testing has been conducted on BPA-free plastics, such as Tritan copolyester, which has been found to exhibit no release of chemical substances during regular use. These tests evaluate the absence of BPA and other bisphenol compounds, as well as estrogenic and androgenic activity. Independent laboratory analysis has also validated the structural integrity of materials like Tritan, demonstrating their compatibility with dishwasher use.

Ziploc containers in freezers
Ziploc containers are a popular option for food storage, including in freezers. They are made of plastic and are BPA-free, addressing potential health concerns associated with BPA, a chemical commonly used in plastic products.
When using Ziploc containers in freezers, it is important to consider the potential for freezer burn, which occurs due to fluctuations in temperature and the presence of air in the container. To prevent freezer burn, it is recommended to remove as much air as possible from the container before sealing it. Pressing out the air or using vacuum sealing can help mitigate this issue. Additionally, ensuring that the freezer maintains a consistent temperature and is not left open for extended periods can further reduce the likelihood of freezer burn.
For optimal results, it is advisable to cool food in the fridge before transferring it to the freezer, especially if it will be stored for more than a month. This helps to prevent frost inside the packaging, which can occur when freezing food that is not already chilled. Chilling food before freezing also applies to dishes intended for use within a week or two.
Meats, in particular, are often sealed in Ziploc bags or vacuum-sealed if they will not be used within a month to prevent freezer burn. For vegetables, pureeing and mixing them into dishes like spicy chili or tomato-based sauces can be a creative solution to utilise their flavour and nutrients while minimising the impact of freezer burn.
Overall, Ziploc containers are a convenient option for freezer storage, and with proper handling and attention to temperature control, users can effectively preserve their food items and prevent freezer burn.

Cleaning Ziploc containers
Ziploc containers are BPA-free, and the brand ensures that its products are extensively evaluated for toxicity and safety. However, it is important to note that plastic is not meant to sustain high heat, as it can cause the plastic to melt or leach BPA. Therefore, when cleaning Ziploc containers, it is crucial to avoid using extremely high water temperatures. Hand washing with warm or cool water is recommended, along with a gentle soap or dish detergent.
To clean your Ziploc containers, start by rinsing them with warm or cool water to remove any remaining food particles or residue. If there are stubborn smells or stains, you can use a mixture of equal parts vinegar and water. Seal the container and leave it for several hours before rinsing and drying completely. You can also use a clean sponge or dishcloth with soap to wipe down the containers. Ensure you reach all the corners and crevices, especially if the container held greasy or oily substances.
For heavier-duty Ziploc containers, such as freezer-quality containers, you can turn them inside out and use a sponge to scrub them thoroughly. Rinse them with warm or cool water and ensure they are completely dry before reusing them. Air drying is the most effective method to prevent mould, mildew, or smells. You can hang the containers from a drying rack or clothesline or let them stand upright to air dry.
While Ziploc containers can be washed and reused multiple times, it is important to note that they are not meant for long-term reuse. Over time, plastic can break down and leach chemicals into your food. Therefore, it is recommended to invest in reusable alternatives such as glass containers, silicone bags, or Tupperware. These options are safer for food storage and more environmentally friendly than repeatedly purchasing single-use plastic bags.
Additionally, it is crucial to avoid reusing Ziploc containers that held raw meat, fish, eggs, or greasy foods. These substances can leave behind bacteria or oily residue, which can be challenging to remove completely and may pose health risks if consumed.
