5 Different Methods of Packaging in Contract Packaging

Ever wondered how contract packaging ensures your products stay safe and look appealing on retail shelves? Packaging isn’t just about aesthetics; it’s a critical protective layer that shields products from damage and keeps them pristine. Whether you’re dealing with delicate cosmetics or heavy-duty items, the method of wrapping plays a significant role in the overall packaging process.

In this post, we’ll explore five distinct wrapping techniques used in contract packaging. You’ll understand how each method is tailored to different needs and products, from shrink wrapping for dust protection to bundle wrapping for heftier items. By the end, you’ll know which wrapping method is best suited for your product, ensuring it not only arrives safely but also catches the consumer’s eye. Dive in to discover how these wrapping techniques can give your packaging the edge it needs.

Shrink Wrapping

Shrink wrapping is one of the most popular methods for packaging products in the retail industry. This flexible and protective wrapping method ensures that the product remains free from dust, fingerprints, and minor damages. The process involves enveloping the product in a clear film that is sealed on all four sides. Once sealed, the film shrinks tightly around the product’s shape when passed through a heat tunnel. This results in a neat, glossy finish that enhances the product’s appearance while offering a layer of protection.

Materials Used in Shrink Wrapping

Shrink wrapping primarily uses two types of films: PVC and polyolefin. Each material has its own characteristics that make it suitable for specific applications.

PVC Film:

• Texture: PVC has a more “wrinkly” feel both before and after the shrinking process.
• Shrink Characteristics: When heated, PVC shrinks uniformly around the product. This material is known for its strong barrier properties, making it suitable for products requiring extra protection from external elements.

Polyolefin Film:

• Texture: Polyolefin has a smoother and softer feel compared to PVC, making it more aesthetically pleasing.
• Shrink Characteristics: Polyolefin provides a consistent, tight shrink around both regular and irregular shapes. It is widely used in the industry due to its high clarity and strong yet flexible structure.

Both PVC and polyolefin films come in various gauges or thicknesses. Traditionally, these films were limited to gauges like 60, 75, and 100. However, advancements have introduced thinner yet durable options like 45 and 55-gauge films. These newer films offer good shrink properties and can sustain the same tensile strengths as their thicker counterparts.

When it comes to choosing between PVC and polyolefin film, several factors come into play, including cost, the appearance of the final wrapped product, and specific protection needs.

Process of Shrink Wrapping

Understanding the shrink wrapping process helps in appreciating its efficiency and effectiveness in retail packaging.

1. Film Selection: The appropriate film type and gauge are selected based on the product’s requirements.
2. Enveloping: The product is enveloped in the chosen film layer, and the film is sealed on all four sides using an “L-bar” sealer or a semi-automated/fully automated machine tailored to production volume.
3. Shrinking: The sealed product then passes through a heat tunnel. Here, the film shrinks tightly around the product, conforming to its contours and creating a snug fit.

This entire process is designed to be rapid and scalable, making it ideal for high-volume retail packaging.

Applications in Retail Packaging

Shrink wrapping finds extensive use in retail packaging due to its versatility and protective qualities. Some common applications include:

• Consumer Electronics: For items like headphones, chargers, and small gadgets, shrink wrapping provides both protection and a polished look.
• Cosmetics: Beauty products such as perfumes and skincare items benefit from the high-end appearance and seal that shrink wrapping offers.
• Food Items: Pre-packaged snacks, confectioneries, and other perishable items often use shrink wrapping to extend shelf life and maintain hygiene.
• Books and Media: Books, DVDs, and other media products are commonly shrink-wrapped to preserve their condition and prevent tampering.

In conclusion, shrink wrapping is a reliable and effective method for retail packaging. It offers protection while enhancing product appearance, making it a go-to choice for various industries.

Flow Wrapping

Flow wrapping is a popular method in contract packaging, particularly for items like coupons, promotional products, and small mail items. The process employs a horizontal form, fill, and seal machine to envelop items in Oriented Polypropylene (OPP) film. Unlike shrink wrapping, flow wrapping does not involve heat, making it a robust choice for delicate items.

Advantages of Flow Wrapping

Flow wrapping offers several benefits, making it a go-to method for various products. Imagine a smooth, clear wrap that not only showcases the product but also keeps it safe and hygienic. Here are some of its standout advantages:

FDA Compliance for Food Products

Flow wrapping is highly suitable for food items. Certain types of OPP film are FDA-approved, meaning they can come in direct contact with food. This makes it ideal for wrapping products like candy bars and breakfast bars. When you see a neatly wrapped granola bar on a store shelf, chances are it’s been flow-wrapped.

Efficiency in Packaging

One of the unique features of flow wrapping is its ability to create a continuous wrap that can be cut into individual pieces or kept on a perforated bandolier. This makes it easier to handle multiple products at once, significantly speeding up the packaging process.

Customizable and Versatile

Flow wrapping allows for easy customization. You can choose between clear film to showcase the product or fully printed film to display your brand’s artwork. This flexibility makes it suitable for a wide range of products, from promotional items to retail goods.

The Flow Wrapping Process

The process itself is fascinating and straightforward:

1. Loading the Product: Items are placed on a conveyor belt, ready to be wrapped.
2. Forming the Film: The OPP film is drawn from a roll and formed into a tube around the product.
3. Filling and Sealing: The machine seals the film around the product horizontally and cuts it into individual packages.

This method ensures a tight, secure wrap, perfect for keeping products safe during transport and storage.

Applications for Promotional Items

Flow wrapping isn’t just for food. It’s also an excellent choice for promotional items such as coupons and small samples. The clear wrap allows the contents to be easily seen, which is perfect for promotional giveaways. Imagine opening a cereal box and finding a coupon or small toy neatly wrapped inside—this is flow wrapping in action.

Types of Film Used

Flow wrapping primarily uses Oriented Polypropylene (OPP) film. This material is known for its durability and clarity. Unlike other films, OPP doesn’t get heated or shrunk, making it more rigid.

• OPP Film: Suitable for food and promotional items, sometimes FDA-approved.
• Clear or Printed Film: Depending on your need, you can opt for a clear film to show off the product or a printed one for brand visibility.

In conclusion, flow wrapping is an efficient, versatile, and compliant method for packaging a wide array of products. With its FDA approval and customization options, it stands out as a top choice in the packaging industry.

Cello Wrapping

When it comes to giving a product that high-end, premium feel, cello wrapping is often the go-to method. This technique is commonly used for items like perfumes, cosmetics, and yes, even cigarettes. What makes cello wrapping unique is its sleek, transparent look and the crisp, tucked ends that scream luxury. Unlike other wrapping methods, cello wrapping offers a tight and professional appearance that many consumers associate with quality products.

Cost Implications of Cello Wrapping

Cost Implications of Cello Wrapping

Okay, let’s talk money. Cello wrapping isn’t the cheapest option out there, and there’s a good reason why. This type of wrapping requires special machines—usually a SCANDIA—which need to be custom-tooled for each box size. Think of it like tailoring a suit; you wouldn’t want an off-the-rack fit for a high-end product, right? This bespoke approach ensures that each package looks immaculate but comes at a cost.

Because of the high tooling expenses, cello wrapping is best suited for products with a higher average selling price (ASP). Here’s why:

• High Initial Costs: The tooling process itself is pricey. You’ll need to invest in custom molds and machine adjustments to ensure every package fits like a glove.
• Higher Per-Unit Costs: Each run will have higher setup costs, which means it’s more economical for high-volume production.
• Premium Appearance: The end result is a sleek, polished look that justifies the higher price tag of the product inside.

So, if you’re selling a $5 product, cello wrapping may not be your best bet. But for a $50 perfume bottle? Absolutely.

Unique Characteristics

Cello wrapping stands out for several reasons, making it a popular choice for premium products. Here’s what sets it apart:

• Crystal Clear Film: The transparency of the film allows consumers to see the product clearly, adding a sense of trust and quality.
• Tight Seal: The wrap hugs the product tightly, giving it a sleek and professional finish.
• Durability: Despite its delicate appearance, cello wrap is quite durable and provides a decent level of protection against dust and minor damage.

Typical Use Cases

Cello wrapping is most commonly used for high-end products where presentation and protection are critical. Here are some typical use cases:

• Cosmetics: Think about your favorite luxury lipstick or high-end face cream. The tight, clear wrap adds a level of sophistication and keeps the product looking pristine.
• Perfumes: A beautifully wrapped bottle of perfume not only looks good but also protects the delicate glass from scratches and smudges.
• Cigarettes: One of the most recognizable uses, cellophane-wrapped cigarette packs, keep the product fresh and intact.

So, if your product needs to look as good as it performs, cello wrapping is worth the investment. The initial costs might be high, but the return in terms of customer perception and product integrity is even higher.

Bundle Wrapping

Bundle wrapping is a method often used for heavy or bundled products. It’s like the big brother of shrink wrapping, providing a robust and reliable way to secure items together. This technique is essential for packaging items that need extra strength and durability.

Design Features of Bundle Wrapping

One of the unique parts of bundle wrapping is the presence of bull’s-eyes. These are open circles at the ends of the package. They are not just for looks; they play a crucial role in handling the package.

Think of bull’s-eyes like handles on a suitcase. They make it easier to pick up, move, and carry heavy or bulky packages. When you’re dealing with a 200-gauge film or thicker, those bull’s-eyes become your best friend. They ensure the packaging can hold the weight without tearing or breaking.

Benefits of Bundle Wrapping

Bundle wrapping stands out for several reasons. Here are its key benefits:

• Durability: The thicker film used in bundle wrapping can handle more weight and stress, making it perfect for bulk items.
• Convenience: Bull’s-eyes make it easier to grip and transport heavy packages, reducing the risk of damage.
• Versatility: It is ideal for various heavy products, from large boxes of goods to multiple items bundled together.
• Security: This type of wrapping ensures that products remain tightly packed and less prone to shifting or breaking during transit.

Heavy-Duty Film Specifications

Bundle wrapping uses significantly thicker film compared to other wrapping styles.

• Film Thickness: Typically, the film is at least 200 gauge. This thickness offers fantastic tensile strength and resilience.
• Material: Often made from durable plastic that can withstand heavy loads.

This kind of film promises strong, reliable protection, much like a suit of armor for your products. It ensures that whatever you’re packaging stays safe, secure, and easy to handle.

Bundle wrapping is more than just wrapping; it’s about securing and protecting heavy-duty products. From its thick film to its handy bull’s-eyes, this method ensures that your larger items get where they need to go—intact and ready for use.

Choosing the Right Wrapping Method

Picking the right wrapping method for your product is crucial. It makes sure your items look great on the shelves and stay safe during transit. But how do you decide which method to use? Consider the type of product, its weight, and how you want it to look for customers. Below, we’ll break down those factors to help you make an informed choice.

Product Type

First, think about what kind of product you have. Is it food, electronics, or a small promotional item?

• Food Items: If you’re wrapping food, you need materials that are FDA-approved and safe for direct contact. Flow wrapping is a great option here as it uses OPP film, which is often food-safe.
• Electronics: For gadgets and tech items, shrink wrapping can offer the protection needed against dust and damage.
• Promotional Items: If you’re sending out coupons or small samples, flow wrapping could be your go-to because it’s efficient and cost-effective.

Product Weight

The weight of your product also plays a significant role in choosing the wrapping method.

• Lightweight Items: Shrink wrapping works wonderfully for lighter items. It gives a snug fit and presents the product nicely.
• Moderate Weight: Flow wrapping is suitable for moderately heavy items like candy bars or breakfast bars. It provides enough stability without adding excessive bulk.
• Heavy Items: Bundle wrapping is ideal for heavier items. It uses a thicker film that can handle more weight and even includes grips for easier handling.

Desired Presentation

How do you want your product to appear on retail shelves? This is where aesthetics come into play.

• High-end Appearance: If you’re aiming for an upscale look, cello wrapping gives a polished finish. Think of how perfumes or luxury cosmetics are wrapped.
• Clear Display: Shrink wrapping is excellent for products that benefit from being fully visible. The clear film contours around the item, making it easy for customers to see exactly what they’re getting.
• Branded Packaging: Flow wrapping allows you to use fully printed OPP film, making your product stand out with custom artwork and branding.

Quick Checklist for Choosing the Right Method
