Plastic Sealer Films

Plastic Sealer Films come in many different sizes, styles, and materials.  We have PP Plastic, PE Plastic, PET-ES Plastic, Aluminum Foil and Paper Films available in both custom print and clear designs.

When choosing your sealing film it is important to make sure that it is compatible with the type of cup or container that you are sealing.  For example, a film like PP will only stick to PP cups while a film like PET-ES film will stick to almost all cups including most PLA Cups.

PP Sealing Films

PP Sealing films are made out of PP Plastic and are only made to be used with PP containers.  They form a strong bond and are not meant to be peeled off.  This type of film is the most common type of film and is commonly used with 95mm PP Cups.

PE Sealing Films

PE Sealer Films are made for Paper Cups that are coated with PE Plastic and can also be used with most (but not all) PP cups.  This film does not create as strong of a bond as PP Films so it is good if you need to peel off the film.  If you do have a container that you want to have the film peel off then we can also create a custom peel-tab for specially designed for your cup or container.

PET-ES Sealing Films

PET-ES Sealing Films are our most versatile films and work for most containers.  It can work with PP Plastic, PET Plastic, Paper, Styrofoam, and most PLA containers.

Paper Sealing Films

Paper Sealing Films are becoming a popular option for replacing plastic sealer films. We coat our paper films in PE plastic so that they remain water-proof.

Paper Sealing Films work with PE Paper Cups as well as some PP Cups.  Also, most paper cups are 90mm so they will need a 90mm sealer machine or a 95mm sealer machine with a 90mm adapter ring.

Paper Sealing Films come in generic print and also custom printing.

Aluminum Foil Sealing Films

This is our first metallic “foil” sealing film that takes our PET-ES film and electroplates it with VMPET material.

Works with cups that are 60mm to 100mm in diameter

PET-ES film works with PP, PET, Paper, PE Paper, and most PLA cups.

Works great for sealing yogurt, cheeses, milk, wine, etc.

Custom Sealing Film

Custom Sealer film is a great way to increase your brand recognition.  Plus since you are ordering the film in bulk (usually 60 rolls) the price per roll comes down a lot!  About $40-50/roll after shipping.

With our custom films, you can have up to 5 colors printed on for free.  The films will take about 30 days to print and then you can either have them shipped by DHL Airmail or Sea Freight.

Here are the main criteria to consider and questions to ask when selecting plastic film for industrial packaging:

The type of load:

What type of product are you wrapping? Is it a dry or wet product? What’s its size and weight? Select film thickness, width, and length according to the size and weight of your products. Also, take into account how smooth they are and possible sharp corners that could tear the film.

The type of plastic:

This depends on the nature of the product to be packed. Commonly used plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polyethylene terephthalate (PET). Each has different properties in terms of strength, transparency, and flexibility.

Desired function:

What will your film be used for? Packaging, protection, heat retention, sealing, etc.?

Some films have specific properties that make them resistant to chemicals, UV, or heat. Others are more transparent. Some also have electrical conductivity properties.

Duration of use:

How long do you expect your film to last, whether in transit or in long-term storage?

Respect for the environment:

More and more plastic films are recyclable or biodegradable. Naturally, we advise you to opt for this type of product for obvious environmental reasons.

In industrial applications, several types of plastic film are used, depending on their specific properties and applications. Here are some of the types of plastic film commonly used:

Stretch film

Stretch film is a versatile material, often made from extruded polyethylene in one or more layers, depending on its intended use. It is known for its flexibility as it can stretch from 125% to 500% of its original length.

There are two main types of stretch film, depending on the extrusion technique used.

1. Cast
   • This film is suitable for standard, even heavy loads with low-profile angles.
   • It offers good adhesion, high lengthwise strength, high transparency, and silent unwinding, and is generally compatible with automatic wrapping machines.
2. Blown
   • This film is suitable for heavy, angular, and uneven loads.
   • It offers very good adhesion, high strength in length and width, limited transparency, the ability to withstand low temperatures, and enhanced durability.

Advantages:

• Strong, puncture- and tear-resistant
• It adheres without sticking to the load.

Disadvantages:

• To effectively secure a load, the stretch film must be carefully stretched, which can make the packaging process more complex.
• However, some stretch film can be pre-stretched before use to simplify the packaging process.

Applications:

• Stretch film is used to wrap and secure pallets of products in the logistics industry.
• It is also commonly used for packaging fresh produce and foodstuffs.

Plastic film is a versatile product whose properties are largely influenced by the plastic of which it is made. Here are the main plastics used in the manufacture of plastic film:

Polyethylene (PE)

It is one of the most commonly used plastics in industry. It can be produced in single-layer or coextruded versions to meet a variety of needs. It shrinks at temperatures of around 150°C.

There are two types of PE: low-density polyethylene (LDPE) and high-density polyethylene (HDPE). PE film is generally 40 to 50 micrometers thick, but thinner versions are available, notably LDPE, which also has non-stick and anti-slip properties.

Advantages:

• PE film is renowned for its moisture resistance.
• It is flexible.
• It is transparent.
• It is the most economical.

Applications:

• Food packaging
• Bulk packaging
• Beverage can packs
• Packaging for furniture, household appliances, etc.

The color of the plastic film is an essential aspect of the packaging. Each color has its own specific use. The color you choose will depend on the company’s needs, the type of products packed, and the environments in which these products are stored or transported.

Transparent film

This is particularly useful for identifying packaged products. In a warehousing or production environment, transparency means you can quickly see which products are contained on pallets without having to remove the film. This improves efficiency and inventory management.

Black film

This provides effective protection against light. It is therefore used to protect light-sensitive products (photosensitive materials, chemicals). In addition, black plastic film offers a degree of privacy, as it conceals the pallet’s contents.

White film

This is similar to black film in terms of light protection. It has the added advantage of effectively protecting products from UV rays. This feature is important for products that could be damaged by prolonged exposure to the sun.

Translucent blue film

This film is commonly used in food packaging. The color blue is often associated with freshness and food safety, making it a popular choice for products intended for human consumption.

Other plastic film colors can be used to help identify products in a storage environment, allowing them to be distinguished at a glance and saving time during order picking. Red, for example, is one of these colors.

Cost can vary considerably depending on film type, thickness, and material. Here are some price estimates for the three main types of film:

Stretch film

Stretch film prices can range from 3 euros to over 100 euros per roll.

For film that is applied manually, prices range from 3 euros to over 50 euros, depending on the size of the roll. Less expensive film is generally suitable for light loads, while more expensive film is suitable for heavier loads or specific uses.
If you wish to apply your film with a wrapping machine, prices range from 30 euros to over 90 euros per roll.

Shrink film

Shrink film is available at prices ranging from 20 euros to over 400 euros per roll.
The price difference depends mainly on the width of the roll (prices increase with width) and the thickness of the film.

Examples:

• Very fine POF (10-15 microns) are more expensive, from 160 euros to 300 euros.
• PE film (40-50 microns) ranges in price from 60 euros to over 120 euros.
• PVC film (20-30 microns) ranges from 50 euros to over 100 euros.

Bubble wrap

Bubble wrap ranges in price from 3 euros to 100 euros for a roll approximately 1 meter long.
