The “Divine Easy-Tease Film” on milk tea cups: Simply peel it off—no sticking to your lips—and it’s packed with cutting-edge membrane technology.

Preface 

“ The bubble tea film tore halfway through, and the milk foam stuck all over my hands. “” Hot drink film comes off and splashes into the mouth. “” The straw keeps brushing against the curled film. — The meltdown exclusive to these milk tea enthusiasts is all due to that unassuming, easy-peel film on the rim of the cup. 

Nowadays, many milk tea shops are switching to... “ Divine beings' film is easy to remove. ” : Pinching “ Little ears ” Simply lift it gently and it separates completely—no sticking to the milk cap, no curling edges, and it’s even capable of printing slogans and QR codes. This film is no longer just an ordinary plastic sheet; it’s a versatile solution that combines sealing, safety, and convenience all in one. “ Membrane Artwork ”。

This article disassembles the easy-peel film of milk tea. “ Past and Present Lives ” From the frustrating issues with old membranes to the cutting-edge technology of new ones—what secrets does this membrane hold? How should consumers and bubble tea shops make their choices? 

I. Let’s Start with a Complaint: Those Years When We Were All Obsessed with Milk Tea and Its Packaging “ Love, hate, and romantic entanglements ”

Before easy-peel films became widespread, milk tea cups mostly used conventional water-based coatings. PE or PVC The membrane appears sealed but actually has numerous defects, severely impacting the user experience. 

(1) Pain Points 1 Difficult to tear, easy to rip. “ Violent film removal ” Become the norm 

The most annoying thing about ordinary membranes is... “ Hard to tear ” There’s no dedicated tear notch—your nails have to dig away for ages before you can even get it open, and as soon as you pull, it just falls apart. Either you’re left with residual film or you end up with the milk cap stuck to your hands, leaving a complete mess all over the place. 

A survey by a certain milk tea brand shows that, “ Difficult to remove the film ” Consistently ranks among the top three in consumer complaints, exceeding... 60% Consumers have been disappointed as a result. Even more dangerous is that if the hot beverage film gets stuck and is pulled forcefully, it can easily splash out and cause burns. 

(2) Pain Points 2 The creamy milk foam sticks to your lips, ruining the taste and making you feel awkward. 

After milk foam tea became popular, the membrane... “ Non-stick ” It has become a must-have. If the heat-sealing temperature of ordinary film gets out of control, the adhesion between the film and the milk cream layer will become too strong, causing most of the milk cream to be pulled off when the film is removed, leaving only the bare tea base behind. 

Some of the membrane edges are rough, and when peeled halfway, they curl into stiff edges. Whenever consumers sip milk tea, the edges keep brushing against their lips—leading to playful teasing from customers. “ Drinking bubble tea feels like wrestling with a membrane. ”。

(3) Pain Points 3 Poor sealing often leads to leaks and spills. 

The ordinary membrane is trapped. “ Easy to tear but difficult to seal. ” The dilemma: Either the seal is too loose, allowing liquid to seep into the cup sleeve when walking; or it’s too tight, making it twice as difficult to remove the film. 

Leakage becomes more noticeable after delivery drinks are shaken during transit. According to data from a certain food delivery platform, among complaints about bubble tea packaging... 45% It's due to poor sealing of the cup mouth membrane. 

II. Decoding the “Black Tech”: What exactly is this easy-peel film made of—easy to tear, non-stick, and leak-proof? 

Mainstream milk tea easy-peel film adopts “ Multilayer composite structure ” By layering materials, we resolve the conflict between sealing and easy tearability—the key secret lies in... “ Material combination ” With “ Process Design ”。

(1) Core Material: A three-layer composite structure, with each layer performing its own specific function. 

High-quality, easy-peel films are mostly... PE/ Adhesive layer /PP” or “PE/EVOH/PP” A three-layer structure, with clear functions for each layer, balancing sealing performance and ease of tearing. 

• Outer layer ( PP Layer) : Support layer, durable 110 Celsius Suitable for hot beverages at high temperatures, with a smooth surface that’s easy to print on. LOGO And the QR code is not easy to fall off. 
• Middle layer (adhesive layer) /EVOH Layer) : Functional core. The adhesive layer controls heat-sealing strength, enabling... “ Easy-to-seal and tear ”； EVOH Enhance barrier properties and lock in fragrance for freshness. 
• Inner layer ( PE Layer) Food contact layer, food-grade PE Non-toxic and odorless, it’s highly flexible and fits snugly around the cup’s rim, providing leak-proof and non-stick protection for the milk cap. 

The state stipulates that food-contact films must comply with: GB 4806.7-2016 Standard, legitimate milk tea shops all have easy-peel films. “ Food contact grade ” Certified—feel free to use with confidence. 

(2) Process Design: 3 A single detail decides. “ Easy to remove ” Experience 

The process design features an easy-peel film. “ Easy to use ” The key is that the peel-off film opens with just one tear—hidden within. 3 A clever idea. 

1. Reserved “ Tear-open small ears ” Precisely apply force without slipping. 

Reserved edge for easy-peel film 1-2 Centimeter “ Little ears ” Tear open, shaped via die-cutting process with smooth edges. Pinch it. “ Little ears ” It can concentrate force and is easy to open without slipping. 

High-end membranes will still be available. “ Little ears ” It has an anti-slip texture, so you can easily grip it even when holding a milk tea. 

2. Control the heat-sealing strength to achieve... “ Easy to open, leak-proof ” Balance 

The core technology is thermal sealing strength control; high-quality film thermal sealing strength. 5-8N/15mm This range is both leak-proof and easy to tear open with moderate force. 

The segmented heat-sealing process achieves balance: the cup mouth edge is sealed at low temperature for easy tearability, while the middle section is sealed at high temperature to ensure a robust seal and prevent leakage. 

3. Optimize membrane tension to prevent the milk cream topping from sticking and curling. 

The non-stick milk cap relies on two key factors: the inner layer. PE Use “ Low surface energy ” The formulation reduces adhesion; the stretching process optimizes membrane surface tension, ensuring a smooth, non-curling peel during removal. 

Testing by a certain company showed that, after optimization, the adhesion rate of the milk cream on the membrane decreased from... 35% Drop to 5% The following. 

III. Consumption Guide: 3 Attract the right match “ Good film ” It’s more comforting to drink milk tea. 

Learning to distinguish between good and bad peel-off masks can significantly enhance your bubble tea drinking experience. 3 Just recruit and you'll avoid pitfalls. 

(1) Check the appearance: Yes “ Little ears ” Printed clearly is more reliable. 

When choosing bubble tea, first check the membrane: it should be smooth. “ Little ears ” A good film has clear printing with no ghosting, while low-quality films tend to fade easily. 

A film with no tear notch, rough edges, and bubble wrinkles is likely to be difficult to tear and prone to leaking. 

(2) Test the feel: Gently pinch it—if it’s resilient and doesn’t crack or become brittle, it’s a good film. 

Gently pinch the film surface before removing it: High-quality films are flexible and will return to smoothness after being pinched; low-quality films are stiff and prone to creases, and are easily torn when removed. 

(3) Check for safety: Be sure to recognize. “ Food contact grade ” Sign 

Transparent cup checkable “ For food contact “GB 4806.7” Labeling: If there’s no label, go for a chain brand—packaging is more strictly controlled. 

Reminder: Don't bite the film with your mouth—it's safer to drink after peeling it off. 

IV. Industry Perspective: The upgrade of milk tea film holds the key to the packaging industry. “ Inward competition ” With innovation 

The upgrade of milk tea film marks a shift in the packaging industry from... “ Can be used ” To “ Easy to use ” Again to “ Combines both looks and functionality. ” A microcosm. 

(1) Functional Upgrade: From “ Sealed ” To “ Multifunctional integration ”

Early membranes were merely sealing and protective; today, they’ve evolved to offer multifunctional integration—features like anti-counterfeiting QR codes, thermal insulation, and biodegradable materials are all now possible. 

Brands like Heytea and Nayuki are already using biodegradable materials. PLA Easy-peel film; also includes brand printing. “ Scratch-off lottery “” Fortune slip ” Let the membrane become an interactive medium. 

(2) Cost Balance: Good membranes don't... “ Your ” The milk tea shop doesn't need to overthink it. 

Consumers don’t need to worry about rising bubble tea prices: Normal. PE Membrane 0.03 Yuan / Zhang, high-quality easy-peel film 0.05–0.08 Yuan / Zhang, each individual sheet only adds a few cents to the cost. 

For milk tea shops, high-quality film can enhance the user experience and reduce complaints. A regional chain brand reported that after switching to a new film, the rate of positive feedback on packaging increased. 28% The repurchase rate is growing in tandem. 

Conclusion 

The happiness of milk tea comes not only from its tea base and creamy topping but also from the smoothness of peeling off the film. Though this easy-peel film may be small, it embodies the technology of film manufacturers and the care of milk tea shops. —— Great products always lie in the details. 

Driven by environmental policies and consumer demand, bubble tea membranes will become more environmentally friendly, smarter, and warmer. In the future, these membranes might even transform into seed cards or commemorative stickers, making drinking bubble tea an even more delightful and surprising experience.
