Custom Double Wall Hollow Structure Biodegradable Paper Coffee Cups With Food Grade PE Coating

Every layer that comes into contact with food deserves to be taken seriously.

Food Grade PE Coated Double Wall Hollow Structure Paper Cups are crafted with food-grade materials from inner lining to outer structure—ensuring your customers can enjoy their hot beverages with complete peace of mind. The double-wall hollow structure keeps hot drinks comfortable to hold, food-grade PE coating guarantees safety in every sip, and custom logo printing lets your brand travel with every cup.

The inner wall features food-grade PE coating (polyethylene), an eco-friendly material widely used in food packaging. Compared to traditional wax coatings or substandard linings, food-grade PE coating offers the following advantages:

• Coating thickness: Uniform 25μm, multi-layer co-extrusion technology ensures no pinholes, no missed areas

• Bond strength: Tightly bonded to paper body, peel strength of 5N/15mm, no peeling, no bubbling

• Coverage: Full inner wall coverage including bottom and rim areas—no dead corners

• Hot drinks: 0°C to 100°C—coffee, tea, hot chocolate, all handled safely

• Cold drinks: From -10°C—iced Americano, iced tea, smoothies, all managed easily

• Acid/alkali resistance: Stable within pH 3-11 range, suitable for all beverage types

Double-wall hollow construction creates a 2-3mm air gap between inner and outer walls:

• Inner wall: Holds the beverage, directly contacts heat source

• Outer wall: Held by customers, transmits temperature perception

• Hollow layer: Air gap that blocks heat conduction

Air is a poor conductor of heat, with a thermal conductivity of only 0.026W/(m·K)—far lower than paper's 0.18W/(m·K). The hollow layer leverages this property, forming a natural barrier between inner and outer walls. When heat transfers from the inner wall to the air layer, most of it is blocked; only a small amount continues outward.

• Filled with 95°C hot coffee for 30 minutes

• Outer wall temperature stabilizes below 45°C—warm but not hot

• No sleeve needed; customers can drink comfortably immediately

The hollow structure also blocks cold-heat exchange. When holding iced beverages, the outer wall temperature remains near room temperature, significantly reducing condensation—no wet tabletops, no damp hands.

The double-wall design not only insulates but also significantly enhances cup strength:

• Double-wall construction delivers 40% higher compression strength

• Cups remain rigid after filling with hot beverages—no softening, no deformation

• Stacked 10 layers for 24 hours: bottom cup shows no deformation

• Triple-rolled rim design, smooth and rounded edges

• Comfortable against lips, enhancing drinking experience

• Reinforced rim strength withstands repeated handling without deformation

Double-layer heat-pressed bottom construction with five-layer protection, bond strength of 6N/15mm—eliminating leakage risks:

• Outer paper wall

• Inner paper wall

• Double PE lining

• Reinforced adhesive layer

Five layers working together form a complete protective barrier. Boba, jelly, popping pearls—load them up. No leaks.

Q: What's the difference between food-grade PE coating and ordinary PE coating?
A: Food-grade PE coating uses virgin materials—pure and clean, FDA/LFGB certified, no odor, no migration at high temperatures. Ordinary PE coating may contain recycled materials, inconsistent quality, and possible odor at high temperatures.

Q: What's the difference between double-wall hollow and double-wall thickened?
A: Double-wall hollow uses an air layer for insulation—more efficient heat blocking, lighter cup weight. Double-wall thickened focuses on compression resistance—increasing paper thickness for strength. This product is double-wall hollow, designed for anti-scald performance.

Q: What temperature can the PE coating withstand?
A: Temperature range -10°C to 100°C—safe for hot coffee, tea, and hot chocolate. Microwave heating not recommended.

Q: Can leak-proof lids be provided?
A: Yes. We offer matching PE or PLA leak-proof lids with snap-on seal design—tested to 45-degree tilt with no leakage. Sold separately.

Q: Are these cups recyclable?
A: Yes. PE-lined paper cups can be recycled according to local waste management guidelines. For a more eco-friendly option, choose our fully degradable PLA bio-based version.

After all these years making paper cups, the feedback we hear most often is: "I didn't know paper cups could be this comfortable to hold."

That simple statement says something important: for many people, burning their fingers on hot drinks has just become normal. Something to tolerate. Something to wait out.

But it doesn't have to be that way.

A good cup should let your customers enjoy that first sip the moment they receive it. And an even better cup gives them peace of mind—knowing that the layer touching their lips is food-grade, safe, and reliable.

If you want your customers to start enjoying your drinks from the very first sip, these food grade PE coated double wall hollow structure paper cups can help make that happen.
