Why Shrink Wrap Is Essential to the Beverage Industry

The beverage industry involves numerous intricate processes. Products must not only be attractive to consumers but also require specific packaging to maintain freshness and ensure safety. Key attributes such as safety, hygiene, and freshness need to be upheld. Shrink wrap is vital for preserving beverages, and here’s why it is so essential.

What Is Shrink Wrap?

Shrink wrap is a protective packaging material predominantly used in the food and beverage industry. This plastic film is flexible and durable, designed to wrap around various objects irrespective of their shape or size. By applying heat, the film shrinks and tightly conforms to the product’s shape, securing it for transport.

As the film shrinks, it closely hugs the product, ensuring everything remains safe and secure during transit. While there are multiple methods to apply shrink wrap, the most efficient is through shrink-wrap machines. These machines wrap, heat, and seal the product simultaneously, eliminating the need for manual processing.

Safe, Hygienic, Fresh

Standard bottle caps and aluminum covers offer insufficient protection for beverages, leading to potential spills and leaks during transportation. More critically, products need to be shielded from contaminants.

No one wants to drink flat soda or open a water bottle to find foreign objects floating inside. Shrink wrap, thanks to its durability and tightness, preserves the beverage’s freshness and prevents contamination. Furthermore, it protects beverages from sunlight, keeping them cool and safe from harmful UV rays.

Marketing Benefits

A significant advantage of shrink wrap is its ability to serve as an additional marketing platform. Companies can creatively use colors, logos, and text to design their shrink wraps. Virtual Packaging provides custom shrink wrap packaging, enabling unique product promotion.

Using shrink wrap also signals to your customers that you value product quality. When shrink wrap is employed, it demonstrates your commitment to delivering the best possible product to your consumers.

Before selecting appropriate films, it’s crucial to identify specific attributes of the product to be packaged. A packaging supplier's role is indispensable in choosing the right film type for your needs. Their expertise helps determine the most suitable films for your product.

Considerations for packaging include:

• Type of product being packaged
• Product weight, shape, and dimensions
• Color and labeling objectives
• Printability of the film to meet your needs
• Packaging method (manual or machine, and type of machine)
• Product journey from creation to shipment and shelf placement
• Handling frequency and potential rough handling
• Environmental conditions the product will face
• Need for specific film additives to maintain freshness (e.g., oxygen or moisture barrier)
• Anti-tampering and security requirements

Various flexible packaging films are available, ensuring you find the perfect match. Whether you need high durability, a higher melting point, or an emphasis on sustainability and recyclability, there’s a suitable shrink film out there. Researching and specifying your needs will help in making the best choice.

You also need to consider your equipment. If you already have or plan to purchase an automatic shrink wrapper, monitor bag lengths and running speeds. Operators sometimes change bag lengths for ease, especially with older pneumatic equipment. Just 1" longer bags can result in 2,000 extra feet of film used daily, equating to about 118 wasted rolls annually.

Assess your maintenance team's capability for regular and ad-hoc technical support. Ensure backup technicians are available if your team can’t handle a repair.

Before purchasing and storing shrink film, understand its storage needs to avoid compromise. Suppliers can provide this information if unclear. Shrink films should be stored between 30 and 77 degrees Fahrenheit, paying particular attention in summer and winter.

Summer

During summer, avoid premature shrinkage by storing shrink films in the coolest areas without refrigeration. Ideal spots are low pallet racks away from windows and high-traffic doors, which have fluctuating temperatures. Schedule deliveries early to avoid the hottest part of the day.

Winter

In winter, prevent films from becoming brittle and cracking by storing them away from doors to avoid moisture and temperature changes. Consider food-safe polyolefin films for frozen products, as they’re more durable than PVC.

Identify compromised film by checking for sticky rolls (overexposed to heat) or sagging. Avoid using these rolls to prevent issues with machinery tracking.

Even top-quality films can deteriorate due to environmental factors. Proper storage ensures products are protected and presented as planned.

Audience

Prioritize your target audience in packaging design. The material used should align with your brand’s message to avoid consumer confusion. Conduct market research to understand customer values and incorporate these with your budget, transport, and sustainability objectives.
