Food Wrap Face-Off: Press’n Seal vs. Traditional Cling Film

Choosing the right food wrap can transform your kitchen experience, making food storage simpler and more effective. For years, traditional cling film has been a household staple, but innovations like Glad Press’n Seal have introduced new possibilities. While both aim to keep your food fresh, they utilize distinct technologies and offer different advantages. Understanding these differences is key to selecting the best food wrap for your specific needs, whether you’re packing lunches, preserving leftovers, or prepping ingredients for later.

Understanding Food Wraps: The Basics

Before diving into a direct comparison, let’s establish a foundational understanding of each product.

Traditional Cling Film Explained

Traditional cling film, often referred to as plastic wrap or Saran wrap, is a thin, flexible plastic film that adheres to itself and surfaces through static electricity. It’s a common sight in kitchens worldwide, used for everything from covering bowls to wrapping individual food items.

Cling film comes in several material types, each with unique characteristics:

• Polyethylene (PE) Cling Film: This is the most prevalent type found in homes today. PE film is generally considered safe, cost-effective, and offers good barrier properties, helping to extend food preservation. It is often microwave-safe, though it’s advised to maintain a gap between the film and food when heating to prevent melting at temperatures above 110℃. PE is also a phthalate-free alternative.
• Polyvinyl Chloride (PVC) Cling Film: Historically, PVC film was popular for its excellent cling strength and clarity. It was frequently used for wrapping raw meats and cheeses due to its good oxygen barrier. However, PVC cling film often contains plasticizers to enhance flexibility and adhesion. Concerns have arisen regarding the potential for these plasticizers to migrate into food, particularly when exposed to heat or oils, leading to health and environmental considerations. Consequently, its use has declined in many markets.
• Polyvinylidene Chloride (PVDC) Cling Film: Best known by the brand name “Saran” wrap, PVDC offers superior oxygen and moisture barrier performance. This makes it an excellent choice for products requiring a longer shelf life and robust protection from spoilage. While highly effective for preservation, PVDC films tend to be more expensive and less flexible than PE or PVC. Environmental concerns and recycling challenges also impact its broader adoption.

Glad Press’n Seal: The Innovative Alternative

Glad Press’n Seal distinguishes itself with an innovative adhesive technology designed to create a tighter, more reliable seal than traditional static-cling wraps. It’s a versatile “food safe plastic film” with a unique gripping ability.

At the heart of Press’n Seal’s effectiveness is its proprietary Griptex® technology. This isn’t just a sticky surface; imagine the wrap having thousands of tiny hills and valleys. The adhesive, which includes FDA-approved ingredients similar to those found in chewing gum, is released and activated only when pressure is applied. This allows Press’n Seal to bond securely to a wide variety of surfaces, including plastic, paper, Styrofoam, metal, and wood, forming an airtight, leak-proof barrier. This pressure-activated sealing mechanism provides a level of security and versatility not typically found in conventional cling films.

Head-to-Head Comparison: Press’n Seal vs. Traditional Cling Film

When it comes to preserving food, both Press’n Seal and traditional cling film have their merits, but they excel in different areas. Here’s a detailed comparison to help you understand which might be better suited for your kitchen tasks.

Adhesion and Sealing Power

The most significant difference lies in how each product seals.

• Press’n Seal: Thanks to its Griptex® technology, Press’n Seal offers a superior, airtight, and leak-proof seal. It bonds firmly to various surfaces, ensuring contents are truly secured, whether in a bowl, on a plate, or even forming custom bags by sealing the film to itself. This strong adherence means liquids are less likely to spill, and air is effectively kept out.
• Traditional Cling Film: Relies on static cling, which often results in a looser, less consistent seal. It can be challenging to achieve a truly airtight barrier, especially on irregular surfaces or when covering liquids. Often, multiple layers or careful manipulation are needed to create an adequate seal, and even then, leaks can occur.

Versatility and Application

Beyond just covering dishes, modern food wraps offer diverse applications.

• Press’n Seal: Highly versatile, it can wrap a wide range of solid and liquid products, including juices, soups, and cooked meals. Its ability to create custom-shaped bags by sealing layers together is a unique advantage. Press’n Seal is also designed to be safe for both microwave and freezer use, making it suitable for various storage and reheating needs.
• Traditional Cling Film: Primarily suited for wrapping solid food items. Its limited clinging ability makes it less reliable for sealing liquids, which can easily spill. While PE cling film can be microwave-safe, it’s generally recommended to leave a gap to prevent the film from touching food and potentially melting. Freezing with traditional cling film can also lead to freezer burn if the seal isn’t perfectly airtight.

Ease of Use

Nobody wants to battle with their food wrap.

• Press’n Seal: Generally considered easy to use due to its reliable adhesion. You simply press it onto the desired surface to create a seal, and it can even be reapplied if necessary. However, some users have reported occasional frustrations with the cutting mechanism on the box or difficulty finding the start of the roll.
• Traditional Cling Film: Can be notoriously frustrating. It often tangles, sticks to itself, and requires careful handling to unroll and apply smoothly. Achieving a tight seal can be a struggle, leading to wasted film and effort.

Durability and Reusability

Consider how long the wrap will last and if it can be used more than once.

• Press’n Seal: Tends to be more rigid and, due to its strong adhesive, can often be reused for light-duty tasks or re-sealed multiple times on the same container.
• Traditional Cling Film: Less durable and generally not designed for reuse. Its thin, often fragile nature means it’s usually a single-use product, contributing to more waste.

Safety and Materials

Food contact materials must meet safety standards.

• Press’n Seal: Is BPA-free and uses FDA-approved adhesive ingredients, offering reassurance for food contact.
• Traditional Cling Film: The safety depends on the material. PE film is widely considered safe. PVC films, while still available, have raised concerns due to plasticizer migration, especially with fatty or heated foods. PVDC films are effective but also face environmental scrutiny. Always check the packaging for specific material information and safety certifications.

Cost

Budget is often a factor in household purchases.

• Press’n Seal: Due to its advanced technology and superior performance, Press’n Seal is typically more expensive per roll than traditional cling film.
• Traditional Cling Film: Generally more budget-friendly, making it an economical choice for those who don’t require the advanced sealing capabilities of Press’n Seal.

Transparency

Visual clarity can be important for identifying contents.

• Press’n Seal: Has a light blue tint, which can slightly obscure the view of the food inside.
• Traditional Cling Film: Is usually highly transparent, allowing for a clear view of the wrapped contents.

Key Criteria for Choosing the Right Food Wrap

Selecting the ideal food wrap depends on a few key considerations tailored to your kitchen habits and priorities.
