Overview of Cling Film Materials
Cling film, commonly known as plastic wrap or food wrap, plays a crucial role in food preservation by adhering to itself and various surfaces to create an airtight seal. This material was first discovered in 1933 and has evolved significantly over the decades. Initially developed from Polyvinylidene Chloride (PVdC), cling film was used to protect military equipment but has since become integral in food safety and storage [1].
Today, the most commonly used materials for cling film include Polyethylene (PE), Polyvinyl Chloride (PVC), and Polyvinylidene Chloride (PVDC). Each type serves different purposes based on its properties and safety levels [2].
Polyethylene (PE)
PE cling film is favored for wrapping perishable items like fruits and vegetables primarily in supermarkets. It is known for being safe for human use and is widely appreciated for its flexibility and food safety assurance. PE film is a product of ethylene polymerization, making it suitable for various food packaging applications [2].
Polyvinyl Chloride (PVC)
PVC is another type of cling film used in food packaging. However, it poses certain health risks as it can contain harmful carcinogens. Despite its effective clinging properties, its use is becoming less favored due to health and environmental concerns [2].
Polyvinylidene Chloride (PVDC)
PVDC cling film is predominantly used for packaging cooked foods and meats like ham. It offers excellent moisture barrier properties and is safe for food contact, making it a reliable choice for preserving food freshness and extending shelf life [2].
In recent years, there has been a shift towards using Low-Density Polyethylene (LDPE) due to its safer profile for human health and lower environmental impact. The “Saran” brand, for example, transitioned to LDPE in 2004 to address these concerns [1].
The choice of cling film material should consider both the functional requirements of the food being packaged and the health implications associated with each type of film. While PVC offers superior cling, its potential health risks make PE and PVDC preferable options for those prioritizing food safety and environmental sustainability.
In conclusion, selecting the right type of cling film involves understanding the properties of different materials and their impact on both food safety and health. By choosing the appropriate cling film, supermarkets, restaurants, and consumers can ensure optimal food preservation while adhering to safety standards.
Functional Requirements
Seal Strength
In the realm of food cling film, seal strength is paramount for maintaining food safety and extending shelf life. The integrity of a seal is influenced by a combination of heat, time, and pressure, which must be perfectly balanced to ensure a robust seal [3]. Various sealing methods are employed depending on the material and the specific requirements of the product. For instance, basic heat sealing utilizes a precise amount of heat and pressure over an optimal duration to achieve a strong bond between the film and the tray [3]. Advanced techniques like impulse heat sealing and ultrasonic heat sealing cater to specific types of thermoplastics and applications, ensuring that the seal integrity is maintained throughout the product’s lifecycle [3].
Modified Atmosphere Packaging (MAP) is particularly sensitive to seal integrity. This packaging technique, often used for perishable products like meats, relies on a specific mixture of gases to preserve the product’s color, texture, and nutritional value. Any compromise in the seal can lead to contamination and spoilage, underscoring the importance of a reliable sealing process [3].
Durability
The durability of food cling film encompasses its ability to withstand various environmental conditions while protecting the food items. Cling film is not only required to have excellent barrier properties against oxygen and moisture but also needs to be resistant to temperature variations. This film is designed to perform under a wide range of temperatures, from as low as -60°C to as high as +160°C, making it suitable for use in microwaves and freezers [4].
The physical properties of cling film, such as tensile strength and elasticity, are crucial for its performance during storage and transportation. Films with higher tensile strength are less likely to tear or puncture, providing better protection for the packaged goods [4]. Furthermore, the film’s ability to cling and form a tight seal without the need for adhesives helps in maintaining the packaged food’s integrity and freshness [5].
In selecting the appropriate cling film for food service applications, one must consider both the seal strength and the durability of the film. These factors are critical in ensuring that the food remains safe and fresh from the point of packaging to the moment it reaches the consumer.
Health and Safety Considerations
Toxicity and BPA-Free Options
When considering the health and safety of cling film, the presence of toxic chemicals is a significant concern. Historically, certain plastics have included harmful chemicals like phthalates and bisphenol A (BPA), which can disrupt hormonal functions and have been linked to various health issues, including cancer and reproductive problems [6]. However, advancements in manufacturing have seen a reduction in these harmful substances. For instance, plastic wrap has been phthalate-free since 2006, although it often contains di(2-ethylhexyl)adipate (DEHA), a plasticizer not classified as a phthalate but similar in structure and potential health risks [6]. DEHA has been shown to migrate into food, particularly high-fat foods like cheese, raising concerns about liver toxicity and tumor formation in mice [6].
Given these risks, many consumers and health advocates recommend using alternatives to traditional plastic wraps. Options such as glass or ceramic containers for food storage and reheating, especially in microwaves, are advised to avoid any contact between plastic and food [6]. Additionally, ensuring that any plastic wrap used is BPA-free is crucial, although it is essential to be cautious, as BPA replacements may not always be safer [6].
FDA-Approved Materials
Ensuring that cling film is safe for direct food contact is paramount, and this is where FDA approval becomes critical. All food-grade plastic wrap, including popular brands likened to Saran Wrap, must meet FDA standards to be considered safe for food contact [7]. This includes being free from toxic chemicals that could leach into food and cause health issues. For instance, perforated cling films used in various food service settings are FDA approved, ensuring they do not pose a direct threat to food safety and can effectively maintain the freshness of the food [8][9].
Moreover, the FDA-approved cling films come in various sizes and thicknesses, typically around 35 gauge, which provides a balance between durability and flexibility, making it suitable for a wide range of food packaging applications [7][8][9]. These products are specifically designed to meet rigorous health and safety standards, providing reassurance to both consumers and food service professionals about the quality and safety of the food preservation materials they use.
Environmental Friendliness
Biodegradability
In the quest for environmental sustainability, the shift towards biodegradable cling films is gaining momentum. Products like the BlknWhite cling wrap, crafted from plant-based starch materials, exemplify this movement. These materials are not only renewable but also compostable, breaking down into water, biomass, and CO2, thus returning to the ecosystem and completing the organic cycle [10]. Certified to international standards, such as ASTM 6400, these compostable cling films ensure food safety while also providing an eco-friendly disposal option [10]. The commitment to reducing plastic pollution is further emphasized by companies that encourage the use of biodegradable alternatives over traditional plastics, aligning with global efforts to protect our planet [10].
Recyclability
Despite the convenience cling film provides, its recyclability remains a significant challenge. Traditional plastic wraps, often made from materials like PVC and LDPE, pose difficulties in recycling due to contamination risks and the complex chemical structures involved [11][12][13].For instance, cling film must be clean and dry to be considered for recycling, and even then, it requires special facilities equipped with LDPE recycling machines that can process the film without it getting stuck in the equipment [13]. The environmental impact of disposing of cling film in general waste is profound, as it can take up to 1000 years to decompose, contributing to landfill overcrowding and increased global warming [13]. Recognizing these issues, some brands are working towards altering their product formulas to reduce single-use plastics, although the effectiveness of these initiatives is yet to be seen [12].
Cost and Availability
Price Points
The cost of cling film varies significantly depending on the type and brand. For example, a pack of three beeswax wraps, known for their sustainability and reusability, is priced at £17.99 [14]. These wraps, while initially more expensive, offer long-term savings as they can last up to a year with proper care [14]. In contrast, restaurant-grade plastic wraps provide a more economical choice. A hefty box containing 2,000 feet of high-quality plastic wrap is available for around $30, offering a cost-effective solution for extensive use in food service settings [15]. This compares favorably to smaller quantities, such as a 200-foot-long roll of typical supermarket wrap, which may cost about $5.00 [16].
Where to Buy
Cling film is readily available both online and in physical stores, making it accessible for both individual consumers and large-scale food service operations. For those looking for commercial-grade film, options include visiting local restaurant supply stores or exploring online platforms where bulk purchases can be made [16]. Supermarkets and online retailers often feature a variety of cling films, including eco-friendly alternatives like beeswax wraps, which can also be found in specialty stores or can be handmade using online tutorials [14]. For specific products like the BeeBee Wraps, consumers can purchase directly from their manufacturing sites in Cambridge or through selected distributors [14].
