The Difference Between LDPE/PLA/CPP As The Innermost Liner For Coffee

Attitudes towards plastic packaging have long been changing. More and more companies and consumers are becoming aware of the environmental hazards it poses. This has inspired roasters to choose more environmentally friendly alternatives. This not only retains customers but also reduces waste.

But the most important thing about bags is to maintain the freshness and quality of the coffee beans.

The most common solution is to add an inner liner to the packaging. This enhances the performance of the coffee bag to better protect the freshness of the beans.

Read on to find out more about coffee packaging liners.



LDPE is a thermoplastic. It is characterised by its thinness, lightness and elasticity. It can withstand temperatures of up to 80°C. It is also odourless, sterile and waterproof. It is also flexible while maintaining structural integrity. This makes it an attractive material for coffee packaging.

LDPE is often used to make packaging films. It can be easily printed for branding information and labelling.

What sets LDPE apart from conventional plastics is the ease and economy of recycling. It can even be made biodegradable with appropriate additives. Unlike polylactic acid (PLA) or kraft paper, LDPE takes approximately the same time to decompose as conventional plastics. And it does not release harmful substances when recycled. This makes it an environmentally friendly alternative

LDPE offers a good balance of options for roasters LDPE offers coffee roasters the reliability of traditional plastics. It also has a much lower impact on the environment.

Things To Keep In Mind When Recycling LDPE

Before using LDPE packaging, roasters should ensure that recycling facilities are available. Brands should inform consumers where to recycle empty coffee bags. But many consumers are not properly aware of recycling.

Companies can encourage consumers to collect their used bags and return them regularly. Roasters can offer discounts or new coffee.

Once the roaster has collected enough bags, the packaging is transported to a special recycling facility. There the bags are extruded, pelletized and moulded into a variety of recycled plastic products.

CPP Film

CPP film is an abbreviation for Cast Polypropylene film. It is a film made from PP plastic using non-directional lamination technology. It is known for providing excellent packaging integrity. It also provides an excellent moisture barrier. This makes it suitable as a packaging material.


CPP is a versatile polymer. It has unique physical and chemical properties.

CPP film has high transparency and gloss. Good sealing properties and lamination strength. It can be printed with flexographic and gravure printing. It can make each package aesthetically attractive. And it stands out with its impeccable heat-sealing properties.

Packaging made with CPP film is resistant to oxygen, UV light and moisture, among other things. It provides additional protection for the coffee. It protects it from external damage.

Recycling Of CPP Film

CPP film is recyclable. It only biodegrades when it comes into contact with soil and microorganisms found in landfills.

One of the advantages of CPP material is that it contains no harmful additives of its own. It is a combination of a CPP film printing layer and a CPP sealing film. This just-right combination gives the CPP film excellent strength and stiffness. This, combined with the film’s neutral odour, makes CPP the ideal choice for coffee packaging.

Features And Benefits Of PLA

Non-toxic And Non-hazardous

PLA is produced by fermenting carbohydrates from renewable sources such as corn, maize starch and sugar cane. The fermentation produces resin filaments that have similar properties to petroleum-based plastics. Yet, it is more environmentally friendly than petroleum-based.

It is one of the most productive bioplastics in the world. The production has a small carbon footprint. And it contains no toxins. Its excellent stability makes it an environmentally friendly material for effective packaging of roasted coffee.

Easy To Recycle

In a controlled composting environment, PLA-based packaging can be decomposed in just 90 days. This compares with 1000 years for conventional plastics. This makes it an attractive option for eco-conscious roasters.

Suitable For Long-distance Transport

The coffee passes through many environments on the way to transport. The tensile strength of PLA means that it can withstand long-distance transport. This makes it an excellent material for coffee packaging.

Personalised Customisation

PLA can be easily customised with different branding and design features. For example, it’s kraft paper to provide a more rustic look. The inside is PLA for added functionality.

Roasters can also choose to add a transparent PLA window so that the customer can view the status of the coffee.

Environmentally Friendly Material

PLA is compatible with digital printing. xiaoyupack uses environmentally friendly inks and glues. We can create fully biodegradable packaging. Sustainable coffee bags help to communicate your commitment to sustainability to consumers. and has the opportunity to increase customer loyalty.


As with all materials, PLA packaging has its limitations. It requires high levels of heat and moisture to break down effectively.

However, PLA is best suited for coffees with a short shelf life. That is coffee that is consumed more quickly. This is because PLA has a shorter lifespan than other plastics. It should be used for coffees that are consumed within six months after packaging.

Specialist coffee roasters can use PLA to package small quantities of coffee.

For recycling PLA, you can encourage consumers to return the packaging. For example, customers who buy coffee in PLA-lined bags can return the empty bags and refill them at a discount.
