PETG Vs. PVC Shrink Film: What'S The Difference?
 

Material Properties
PETG Shrink Film: PETG is a transparent thermoplastic polyester film. It has high clarity, allowing for excellent product visibility. PETG has good tensile strength and toughness, making it resistant to tearing or puncturing. It also has excellent dimensional stability, meaning it retains its shape and size after heat shrinking.PVC Shrink Film: PVC is a versatile thermoplastic film known for its clarity, flexibility, and shrinkage properties. PVC shrink film is available in various thicknesses and grades. It has good shrinkage characteristics, allowing it to conform tightly to the shape of the product being packaged.

 

Clarity and Appearance
PETG Shrink Film: PETG offers exceptional clarity, resulting in a high-quality, transparent packaging solution. The film allows the product to be clearly visible, enhancing its presentation and appeal on store shelves. PETG shrink film does not yellow or becomes brittle over time, maintaining its appearance even after extended periods.PVC Shrink Film: PVC shrink film also provides good clarity, although it may not be as crystal clear as PETG. However, PVC shrink film offers a glossy and smooth finish after heat shrinking, giving products an attractive appearance.

 

Shrinkage Properties
PETG Shrink Film: PETG has low shrinkage properties compared to PVC. It typically shrinks at a lower temperature and with less force. PETG offers controlled and consistent shrinkage, making it suitable for heat-sensitive products or those that require more gentle shrinkage.PVC Shrink Film: PVC shrink film has high shrinkage properties, enabling it to conform tightly to the shape of the product. It provides excellent shrinkage at lower temperatures, resulting in quick and efficient packaging.

 

Environmental Considerations
PETG Shrink Film: PETG is considered more environmentally friendly than PVC. It is a recyclable material, and some PETG shrink films are manufactured using recycled content. PETG does not emit chlorine or other harmful gases during the heat-shrinking process.PVC Shrink Film: PVC shrink film is not as environmentally friendly as PETG. PVC contains chlorine, and when heated, it can release chlorine gas, which is harmful to the environment. PVC shrink film is not easily recyclable, and improper disposal can contribute to environmental pollution.

 

 
 
What Are the Characteristics of PETG Shrink Film?
01.

Transparency

PETG shrink film is highly transparent, allowing for excellent product visibility. This property is particularly advantageous for retail packaging, as it enables customers to see the product inside without opening the package. The clarity of PETG film helps enhance the visual appeal of packaged items.

02.

High Shrinkage

PETG shrink film has a high shrinkage ratio, meaning it can tightly conform to the shape of the product when heated. Upon exposure to heat, PETG film shrinks evenly and uniformly, resulting in a snug, protective wrap around the item. This property ensures a professional and attractive appearance of the packaged product.

03.

Excellent Printability

PETG shrink film is compatible with various printing methods, including flexographic, gravure, and digital printing. It allows for vibrant and high-quality graphics, branding elements, and product information to be printed directly on the film.

This property is particularly crucial for products with sharp edges or corners.

 

How to Choose PETG Shrink Films

 

Understanding PETG Shrink Film

PETG (Polyethylene Terephthalate Glycol) shrink film is a type of thermoplastic polymer known for its excellent clarity, recyclability, and durability. It is widely used for packaging due to its shrink properties when exposed to heat, creating a tight and secure seal around the packaged item.

 

Consider the Application

Identify the specific application for which you intend to use PETG shrink film. Whether it's for wrapping individual products, creating multi-packs, or labeling, understanding the intended application will guide you in choosing the right thickness, size, and shrink characteristics.

 

Film Thickness

The thickness of PETG shrink film is an important factor. Thicker films offer increased strength and durability, making them suitable for heavier or bulkier items. Consider the weight and size of your products to determine the optimal film thickness for your packaging needs.

 

Shrink Characteristics

PETG shrink film exhibits different shrink characteristics based on its formulation. Some films offer a high shrink percentage, providing a tight and secure wrap, while others may have lower shrinkage for more gentle packaging. Choose a film with shrink characteristics that align with your packaging requirements.

 

Clarity and Printability

The clarity of PETG shrink film is crucial, especially if your products have labels or graphics that need to be visible after packaging. Additionally, consider whether you need the film to be printable for branding or product information. High clarity and printability contribute to an aesthetically pleasing package.

Resin drying
First, dry the PET copolymer resin. Take the BOPET film production process as an example. Then add it to the extruder for melt extrusion, cast it through the die head cold drum, and then heat the blank to above the glass transition temperature and below the melting temperature. Under the action of external force, stretch it unidirectionally or bidirectionally. Usually, it needs to be stretched 3.5~4.0 times in the transverse direction.

 

Stretching
The PET macromolecular chain is oriented along the direction of the external force by stretching, and then cooled and shaped to "freeze" the oriented PET molecular structure. The high elastic deformation produced under the action of external force has a thermal shrinkage memory effect. When the film with "memory effect" is heated to above the stretching temperature again, the macromolecular orientation structure is frozen and begins to relax, and the PET film shrinks.

 

Heat shrinkage
It is worth mentioning that the thermal shrinkage of this PET film is mainly contributed by the oriented amorphous part, which is also the reason why the copolymer modified amorphous PET film (APET or PETG) has better thermal shrinkage than ordinary crystalline PETG shrink film. Therefore, by increasing the orientation of the amorphous region in the film, the purpose of greatly increasing the thermal shrinkage of the film can be achieved. As mentioned above, the thermal shrinkage of ordinary polyester film is only less than 30%, while the thermal shrinkage of copolymer modified polyester can reach more than 70%.

 

Secondary molding
PETG heat shrink film was originally produced by secondary molding process, that is, the powder is plasticized and granulated once, and the film is blown by secondary plasticization. This method adds sufficient stabilizers and lubricants, so the production cost is relatively high. In addition, due to the one-time plasticization process, the product is contaminated during the production process, affecting the yield. With the development of my country's plastics industry, the application of plastic products has penetrated into various fields, especially in packaging. Plastic products are replacing other packaging materials with their high quality and low price. PETG heat shrink film has been widely used as a packaging material, and the use of food, medicine and daily necessities has increased sharply.

FAQ
 

Q: What is PETG shrink film?

A: PET Shrink film- Polyethylene terephthalate (PET) Shrink film combines high density and strength into a high quality option. PET Shrink film made of PETG , also called PETG shrink film,PETG heat shrinkable film ,is the best Shrink film material so far, It is recyclable, eco-friendly material.

Q: Does PETG shrink?

A: PETG has a glossy surface, adheres greatly to a print sheet, and does not shrink or warp (it has very little thermal expansion), therefore it's suitable for printing large models. Plus, its high tenacity and flexibility often prevent it from breaking.

Q: Why is PETG so hard to print with?

A: Most PETG users would agree that the single biggest disadvantage of the printing material is its tendency toward oozing (when material seeps from the nozzle) and stringing (when the seeping material forms a weblike mess across the part) — undesirable phenomena caused by the low viscosity of the plastic.

Q: Does PETG degrade?

A: PETG is an industrial-grade 3D printing material designed to work in extreme environments. It's resistant to oils and greases. The filament doesn't degrade over time and immune to UV light. Use it to test your prototypes in various industrial conditions.

Q: What can I use instead of shrink sleeves?

A: Wraparound labels, also known as pressure-sensitive labels, are applied to the product container by pressure rather than heat. These labels come on rolls and are typically made of paper or film. Pros: Cost-effective production: Wraparound labels are generally more cost-effective to produce compared to shrink sleeves.

Q: What is the difference between PETG and HDPE?

A: Both HDPE and PET have good strength properties-although the specific strength characteristics differ. HDPE is known for its higher tensile strength and impact resistance. This makes it better suited for containers and products that are likely to undergo sudden impacts. PET is still strong but not as rigid.

Q: How thick is PETG film?

A: PetG -standard format foil on a roll 0.3 mm / 300 μm thickness, 300 mm wide. These rolls are available separately in rolls of 50 kg and are available from stock. The PetG rolls are often used for, for example, the vacuum forming of blister packs, packaging, trays and moulds.

Q: Does PETG get brittle over time?

A: Dry Filament: Moisture can make PETG brittle. Store filament in a dry box or use a filament dryer before printing.Similar to ABS, PETG requires much hotter temperatures than PLA. In general, the hot end should be heated to between 220 and 250 °C. If the layers of the print don't adhere, your temperature is too low.

Q: What are the downsides to PETG?

A: Despite its many advantages, PETG is not without its challenges. It is more difficult to print with than PLA, requiring careful calibration of the printer and often a heated print bed. PETG is also more prone to stringing and oozing, where excess material is left behind as the print head moves.

Q: Why is PETG not recyclable?

A: For years, some PETG manufacturers have been putting a recycling code of 1 on their products, lumping PETG in with PET (also known as PETE). But, alas, these two plastics are cousins, not siblings, and the glycol-modified PETG does not cleanly melt in recycling like the PET does, and that fouls up the machines.

Q: Why use PETG instead of PLA?

A: PLA provides a smooth, glossy finish suitable for prototypes, while PETG offers superior strength and flexibility, making it ideal for functional parts. Printing with PLA is user-friendly due to lower temperatures, while PETG requires higher temperatures and a heated bed.

Q: Is PETG safe to print without enclosure?

A: PETG prints without any order and emits almost no toxic fumes during the printing process. This makes it easy to print the material without any enclosure or need for an air filter. You can print PETG inside your homes or workspace without worrying about any health-related side effects.

Q: Can you drink out of PETG?

A: PETG Plastic Is Safe To Use.As just discussed PETG material, unlike other popular plastics, is known for its non-toxic and odorless emission. With that in mind, PETG fumes are safe to breathe, so it's safe to use in 3D printers indoors and is also safe to use in food containers and beverage bottles.

Q: What is the difference between PET and PETG shrink film?

A: While like PET, it is more robust and durable, has more significant impact resistance, and is better suited for higher temperatures shrink sleeves. In addition to these characteristics, PET-G is well-suited for conversion techniques such as sheeting, slitting, and guillotining for further conversion.

Q: What is the manufacturing process of PETG film?

A: Extrusion: The selected PETG resin pellets are melted and extruded through a die to form a continuous thin film. This extrusion process creates a flat, flexible sheet of PETG material with uniform thickness. Cooling: The extruded LDPE film is then cooled rapidly to solidify it into a stable state.

Q: What is the manufacturing process of PETG?

A: PETG is produced using a two-step, melt-phase polycondensation process. This relatively simple process joins two different monomers together, accompanied with the release of a small molecule such as water. PETG can be injection moulded, sheet extruded or extruded as a filament for 3D printing.

Q: How is PETG shrink film manufactured?

A: PETG materials are plasticized and melted in an extruder after being dried and are extruded into a uniform membrane by a T-shaped die head. The membrane is quenched and shaped on a cooling roller, and is longitudinally stretched by the ratio of 1:1.1-1.5 after being preheated by seven preheating rollers.

Q: What is the formula for shrink film?

A: The formula for this is H+W+2. Tubing: Tubular shrink film is typically only used for oblong objects. To determine the width of your shrink film tube, multiply the circumference of your object by 1.15, then divide your total by 2. In other words, (CIR×1.15)÷2.

Q: What is the chemical composition of shrink film?

A: Shrink Wrapping uses three major types of films to protect and secure products for retail and shipping environments: polyvinyl chloride, polyolefin, and polyethylene. Each of these materials has its capabilities and qualities that make it ideal for specific applications.

Q: What is the difference between LDPE film and HDPE film?

A: Both LDPE and HDPE are polyethylene types. The difference between the two types is that LDPE is made under high pressure, in contrast to HDPE. LDPE has many more side branches in its molecular structure, which gives LDPE a good tear strength in the transverse direction.
