What Is PP Luggage?

 

 

Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.

Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling.

Mold design
The mold for the luggage is designed and manufactured based on the desired size and shape of the luggage.

Injection molding
Once the mold is ready, the PP plastic is injected into the mold cavity at high temperature and pressure.

Cooling
After the plastic is injected, it is left to cool and solidify in the mold.

Ejection
Once the plastic is cool and solid, the mold is opened and the finished luggage is ejected.

Trimming and finishing
The excess plastic is trimmed and removed, and any necessary finishing touches are made.

Assembly
The luggage is assembled by attaching handles, wheels, zippers, and other fittings.

Quality control
The finished luggage is subjected to quality control tests to ensure that it meets the required standards before it is shipped out to customers.

What Is Polypropylene?

Polypropylene (PP) is a semi-crystalline thermoplastic made from the polymerisation of propylene monomers. Otherwise known as polypropene, its chemical formula was discovered in 1951 by Paul Hogan and Robert Banks before being refined into a resin for mass production by Professor Giulio Natta in 1954.

Polypropylene is widely used in its homopolymer form, which contains only propylene monomers. Adding ethylene into the polymerisation process creates PP copolymers. These have slightly different characteristics to the virgin material, including varying melting temperatures between 130°C and 170°C.

PP random copolymers are made when ethylene or butene bonds are introduced in the polymer chain and up to 6% of the polymer's mass is ethene that's spread at different points on the molecular chain.

PP block copolymer is when 5% to 15% of the mass is ethene integrated in a regular pattern across the chain.

 

Applications Of PP Plastic
 

Material handling

Polypropylene is often used to make plastic pallets and other material handling goods depending on their required applications.

Automobile industry

Polypropylene is frequently used in manufacturing car batteries, bumpers, interior elements, and cladding.

Packaging material

Due to its low cost and flexibility, PP is used in various packaging forms and has replaced traditional materials such as paper, cellophane, and paper. It is widely used to make pallets, bottles, jars, yogurt containers, hot beverage cups, food packing, etc.

Toys

Many toys are built-to-last because they’re made using polypropylene plastic.

Housewares

PP is also used in many household items such as rugs, mats, carpets, plates, etc.

Medical applications

With its ability to handle stringent sterilization procedures, PP is commonly used in the medical industry. It's often used in building medical devices, and packaging systems for liquid and solid pharmaceuticals.

 

What Are the Main Differences Between Abs and PP Luggage?

Durability

Both materials are durable, but ABS is known for being more impact-resistant than PP. If you're someone who travels frequently and wants a bag that can handle rough handling, ABS may be the better option.

Weight

ABS and PP are both lightweight materials, but ABS tends to be slightly heavier. If you're looking for a bag that won't weigh you down, PP may be the better option.

Texture

PP has a smoother texture than ABS, which can make it less prone to scratches and scuffs. If you're someone who wants a bag that will look newer for longer, PP may be the better option.

Flexibility

PP is more flexible than ABS, which can be beneficial for those who need a bag that can easily be squeezed into tight spaces. If you're someone who travels with a lot of gear and wants a bag that can accommodate all of it, PP may be the better option.

 

Find the Luggage Material That Suits Your Needs

ABS (Acrylonitrile Butadiene Styrene)
ABS (Acrylonitrile Butadiene Styrene) is a common thermoplastic polymer used in hard cover luggage. It is lightweight and durable, but not as strong as other materials. Due to the non-flexible nature of ABS, these suitcases have a higher tendency to develop cracks in the hard case. ABS is also prone to scratching and scuffing.
PP (Polypropylene)
PP (polypropylene) is another lightweight and durable material. It is known for its resistance to impact and temperature changes, but not as durable as other materials. PP luggage is slightly more expensive than ABS.
ABS/PC composite
ABS/PC Composite is a blend of ABS and PC, offering the benefits of both materials. The combination results in a more durable and lightweight luggage option, while still being scratch-resistant. This material is somewhat durable (not as durable as polycarbonate, but more durable than regular ABS).
PC (polycarbonate)
PC (polycarbonate) is a premium material used for hard cover luggage. It is extremely lightweight, yet strong and durable. The first thing that you would probably notice is that a PC luggage is really flexible, which makes it much more resistant to cracks and durable. With that said, the weight difference is only very minimal (only 12% heavier than the lightest luggage plastic – polypropylene). No doubt that PC is the material of choice for many high-end luggage brands, and for good reason.
PET (polyethylene terephthalate)
PET (polyethylene terephthalate) is a newer material used for hard cover luggage. It is eco-friendly, as it is made from recycled plastic bottles. In terms of durability, it's comparable to ABS, which means that it isn't really too durable. PET is a great option for those looking for an eco-friendly luggage choice.
Aluminum
Aluminum is the most durable material out of all and scratch-resistant. However, it is the heaviest material used in luggage (37% more than polycarbonate) and not as impact-resistant as other materials. As aluminum luggage is easily dented and expensive, it's not as popular as polycarbonate for luggage. Aluminum luggage is often associated with luxury brands and a sleek, stylish look.

Alternative Materials to Polypropylene and Polyethylene

Listed below are some alternative materials to both polypropylene and polyethylene: 

Polystyrene: Polystyrene is a rigid thermoplastic polymer in the polyolefin family. It can be made from a variety of monomers, the most common being styrene. Injection molding is used to manufacture many polystyrene products. Polystyrene is commonly used in packaging, insulation, and construction.

 

Polyvinyl Chloride (PVC): PVC is a thermoplastic polymer that belongs to the polyolefin family. Vinyl chloride is the most common monomer used in its production. PVC can be produced in both rigid and flexible variations and is often seen in the form of pipes, cables, and window frames. Dioxins are created as by-products of the PVC production process, which can have negative effects on the environment.

 

Polycarbonate: Polycarbonate is a thermoplastic polymer that belongs to the polyolefin family. It can contain a variety of monomers, the most common of which is bisphenol A. Polycarbonate is often used as a substitute for polypropylene in applications that require both impact resistance and transparency.

FAQ

Q: Is polypropylene good for suitcase?

A: Polypropylene is one of the strongest materials and is therefore also used in making Curv. The hard shell can withstand a strong impact. It is a good alternative for travelers who find the bags made of polycarbonate or Curv too expensive.

Q: Are polypropylene bags good?

A: Woven polypropylene bags are strong and durable, making them an ideal choice for packaging a variety of products. These bags offer excellent protection against moisture and other environmental factors, ensuring your products stay safe and dry during storage and transport.

Q: Should I avoid polypropylene?

A: Polypropylene is generally considered safe for use, but you should still be wary of using plastics more often than you have to. The chemicals found in plastic products are proven to contribute to some cancers. While it's nearly impossible to avoid all plastic products, you can use as little plastic as possible.

Q: What is the strongest material for luggage?

A: Other than aluminum luggage, polycarbonate is the most durable luggage material. Although it's one of the lighter industrial metals, aluminum luggage tends to be heavier than polycarbonate luggage.

Q: Which suitcase is better polycarbonate or polypropylene?

A: When comparing polypropylene vs. polycarbonate bags such as the Platinum® Elite Medium Check-In Expandable Hardside Spinner, it's important to remember that while polypropylene is lighter, polycarbonate is the sturdier choice. A polycarbonate suitcase may cost more but will offer more rigid protection.

Q: Is polypropylene better than stainless steel?

A: Polypropylene can even perform better than stainless steel when dealing with heat simply because it does not conduct heat. So, if you are working with hot items, the work surface will not become hot and add to the heat in your application. The polypropylene surface will lend temperature stability to your application.

Q: How long does polypropylene last?

A: 20-30 years
Once in landfills, polypropylene slowly degrades and can take anywhere from 20-30 years to totally breakdown. This characteristic poses massive environmental concerns because the additives used in the manufacturing may include toxins like cadmium and lead.

Q: What destroys polypropylene?

A: When burnt or incinerated, polypropylene will only give off water vapour or carbon dioxide, which is converted by photosynthesis (chlorophyll). To incinerate some materials, extra fuel needs to be added – polypropylene, however, is destroyed simply by burning because its calorific capacity is similar to that of oil.

Q: What type of luggage is best for travel?

A: Hard-Shell Luggage
Today's hard-shell, or hard-sided, luggage is often made of high-tech plastics, such as polyethylene, ABS, and polycarbonate, which are lightweight and durable. ABS is lighter, but polycarbonate is more durable. The most durable, but also the heaviest, is aluminum.

Q: What is the best material for luggage for international travel?

A: Look for lightweight construction
For softside suitcases, polyester and nylon materials are often the most lightweight, while hardside shells made of polycarbonate, polypropylene, and ABS are great options as well.

Q: What material is best for hardside luggage?

A: Polycarbonate has high tensile strength and is extremely long-lasting. Of all hardside, plastic suitcase materials, it is by far the most durable.

Q: Is polypropylene high quality?

A: Cost-Effective: Polypropylene is an affordable material compared to other thermoplastics such as ABS and polycarbonate, making it a popular choice for many applications that require a high-quality yet cost-effective material.

Q: What is better than polypropylene?

A: Nylon, as noted by its higher melt viscosity, is more heat-resistant than polypropylene. Nylon is also a low-friction plastic, which makes it ideal for creating parts used in high-friction industrial applications.

Q: Does polypropylene yellow over time?

A: In the majority of plastics, yellowing is spontaneous and cannot be stopped. The time to have a certain degree of yellowing or degradation relates to the type of plastic and its application. Commodity Plastics like polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC) are at increased risk.

Q: Can polypropylene be microwaved?

A: Polypropylene is microwave safe. It has a temperature tolerance of 0 to 250 degrees before distortion. It's most commonly used for containers, plates, bowls, cutlery and catering trays.

Q: Does polypropylene give off microplastics?

A: Here, we show that PP IFBs release microplastics with values as high as 16,200,000 particles per litre. Scenario studies showed that PP IFB sterilization and exposure to high-temperature water significantly increase microplastic release. A 21-d test of PP IFBs showed periodic fluctuations in microplastic release.

Q: How do you protect polypropylene?

A: However, using additives and coatings can help protect polypropylene parts from sunlight. For example, zinc oxide or titanium oxide fibers can block and absorb UV light, reducing the polypropylene's exposure to UV radiation and extending the part's life.

Q: What to avoid when buying luggage?

A: Pay close attention to the things that usually break when you need them the most: wheels, straps/handles, and zippers. Make sure you visually check the seams, stitching, and hardware. And never buy luggage with tiny wheels. They won't last more than a few trips, and that luggage is basically disposable.

Q: Which is better hardside or soft sided luggage?

A: Consider hard-shell luggage if you want durable, easy-to-maneuver luggage with a robust exterior to protect your valuables. Soft-shell luggage can be for you if you're seeking versatility, ease of packing, and a big interior.

Q: Why is Hardside luggage so popular?

A: One of the most appealing factors of hardside luggage is the sleek design. The shell is typically protective enough to safeguard your belongings during rough airport baggage handling, in-flight turbulence, or rainy delays on the tarmac, making the investment worth it for peace of mind.
